5 Sneaky Tricks Grocery Stores Use to Make You Spend More Money

You go in for a loaf of bread, and you come out with $100 worth of groceries. How does it happen? Grocery store psychology. From the layout to the music, stores use a number of strategies to manipulate your senses and encourage spending. When you know what to watch out for, you can make sure you stick to your budget.

1. “OPEN THE WALLET” PRICING


You’ve seen this in action: those grocery store endcaps that advertise an amazing deal on gummy bears. Do you need gummy bears? Probably not. It doesn’t matter; low prices get you in the mood to spend.

“[This] is the technique of pricing items really cheap in the front display aisles at retail and grocery stores to get your brain excited about saving a bunch of money,” says Kyle James, a retail expert and founder of RatherBeShopping.com. “It’s psychological warfare and your money is at risk. Namely, spending money on stuff you had no intention of buying but simply can’t pass up as the ‘deal’ is just too good.”

James points out that Target infamously uses this tactic (think of their bargain bins at the front of the store). “Open the wallet” pricing totally explains the Target “we just need one thing” phenomenon.

2. MAZE-LIKE LAYOUTS

Grocery stores don’t design their layouts haphazardly—a whole heap of psychology goes into it. For example, ever feel like you have to walk miles to get to the dairy fridge? That's because you practically do. National Geographic’s The Plate explains:

Dairy departments are almost invariably located as far from the entrance as possible, ensuring that customers—most of whom will have at least one dairy item on their lists—will have to walk the length of the store, passing a wealth of tempting products, en route to the milk, eggs, cheese, and yogurt.

It’s the same idea as the “Boomerang Effect.” With this strategy, grocers place popular items and brands in the middle of store aisles so that customers have to walk past other, unneeded items to reach them, no matter which direction they’re coming from. In other words, grocery stores make it purposely difficult to simply get in and out with what you need. They do everything they can to lure you with their products.

“If you're only running in for milk and eggs, don’t grab a cart or basket,” James suggests. “Instead, carry your milk and eggs in your hands. This way you won’t be tempted to throw impulse purchases into your cart. You can’t buy what you can’t carry.”

3. CHARM PRICING

Charm pricing is another notorious grocery store trick, and James explains what happens when we see this in action.

“Whenever you see a product priced at $29.99 or $9.98, the store is attempting to ‘charm’ your brain by marking prices just below a round number,” James says. “Because our brains are trained to read from left to right, the first digit is the one that sticks in our head and the number we use to decide if the ‘price is right.’ This phenomena is known as the 'left-digit effect' and studies have shown that it absolutely works and has a big impact on our buying decisions.”

He offers an easy trick for combating this. Whenever you see a price ending with .99 or .98, round up, then decide if it’s a good deal. “By knowing exactly what these stores are trying to do, you can walk by these ‘trick your brain’ displays and stay focused on the reason you walked in.”

4. PLACING EXPENSIVE ITEMS AT EYE LEVEL

If you’re looking to save money, look down. Many grocery stores place their most expensive items at eye level and place the bargain buys and generic brands on the bottom shelves. This helps guide you toward the pricier items, since they’re literally right in front of your face.

However, walk down the cereal aisle and you’ll probably notice that flashy brands like Cap’n Crunch are placed on lower shelves. In this case, stores are hoping to catch the eyes of younger consumers—namely, your kids. Research from Cornell found a link between eye contact (in this case, between children and spokes-characters) and consumers’ positive feelings toward a product. For example, here’s how consumers responded to a strategically placed box of Trix cereal:

Findings show that brand trust was 16% higher and the feeling of connection to the brand was 28% higher when the rabbit made eye contact. Furthermore, participants indicated liking Trix better, compared to another cereal, when the rabbit made eye contact. This finding shows that cereal box spokes-characters that make eye contact may increase positive feelings towards the product and encourage consumers to buy it.

To combat this trick, look around at all of your product options, top and bottom shelves included. Simply being aware of this strategy will go a long way toward blocking its effectiveness.

5. BACKGROUND MUSIC

Music seems harmless enough, but it’s another highly effective tool for getting customers to spend more. A now-famous 1982 study published by the American Marketing Association [PDF] found that sales increase and people spend more time shopping in stores playing music. The type of music matters, though. The study reported:

The tempo of instrumental background music can significantly influence both the pace of in-store traffic flow and the daily gross sales volume purchased by customers, at least in some situations. In this study the average gross sales increased from $12,112.35 for the fast tempo music to $16,740.23 for the slow tempo music. This is an average increase of $4,627.39 per day, or a 38.2% increase in sales volume.

Of course, those results only apply to that specific study, but the point is: There’s research that shows music can indeed influence shopping behavior. And you can bet grocery stores use this to their advantage.

36 Unusual Units of Measurement

When it comes to measurement, we have a lot of words that mean a bunch of stuff or a bit of something, but many of those terms have actual, specific meanings.

Let's learn about a whole barrel full of them.

1. A barrel changes depending on what's in it.

When you're talking about oil, a barrel is exactly 42 gallons. For beer, a barrel is 31.5 gallons. For dry goods, it's 105 dry quarts. That last one was defined by Congress in 1915.

2. A dash is part of a teaspoon.

Then there's the dash, as in, "just a dash of salt," which is between 1/16 and 1/8 of a teaspoon.

3. A pinch is part of a dash.

A pinch is half a dash, or 1/16 of a teaspoon.

4. A Smidgen is a real thing.

It's a half of a pinch, or 1/32 of a teaspoon.

5. Pats of butter are 1/3 of an ounce.

Butter is packaged at 48 pats per pound, which means that each pat is 1/3 of an ounce or 1 tablespoon.

6. A drop is 1/480 of a fluid ounce.

Okay, to be more specific, it's .05 milliliters, which you probably already knew if you're a pharmacist.

7. Australians used to measure rain by points.

We don't measure rain by drops, but in Australia, they used to measure rain by points. A point was .254 milliliters, so you might say, "We got a hundred points of rain last night!," which sounds like a lot, but isn't.

8. The Jiffy is about 10 milliseconds.

Computer circuit board

The jiffy is a unit of time used in computer engineering that has to do with a computer's clock cycle. It's about 10 milliseconds. It means something even faster in physics, where a jiffy is a unit of measurement for the time it takes for light to travel a distance the size of a nucleus.

9. A Shake is 10 nanoseconds.

Physicists also have the shake, which is used to measure nuclear reactions. A shake takes 10 nanoseconds, or 10 billionths of a second, so the next time you go somewhere for the weekend, you can tell friends you'll be gone for 17,280,000,000,000 shakes.

10. A hogshead was 63 gallons.

Specifically, 63 gallons of wine. It's a term dating back to at least the 15th century, and it might be a corruption of the term hog's hide, which might make clearer sense for referring to a wine container, but we really don't know how the word came about. The casks are also repurposed to mature whiskey.

11. You can have a double hogshead ...

It's called a port pipe, and it holds about 145 gallons.

12. ... or a butt.

A butt holds about 132 gallons, so when someone tells you that they drank a buttload last night, they are either lying or dead.

13. Megadeath is a unit of atomic bomb destruction.

Megade(a)th is not just the third-greatest heavy metal band of all time. It's also a terrifying unit of measurement. It was coined in the '50s as a unit of atom bomb destruction. One megadeath is equal to one million deaths.

14. A micromort measures the probability of death.

On the other end of things, we've got the micromort, a unit for measuring the statistical probability of death. One micromort is a one-in-a-million chance of death. So, smoking 1.4 cigarettes, or spending an hour in a coal mine increases your risk of death by precisely one micromort. Going skydiving? Seven micromorts. They're the coolest thing—and also the only cool thing—ever invented by actuaries.

15. manpower is about 1/10th as powerful as horsepower.

So you've heard of horsepower, but did you know there's also a measurable unit of manpower? It was worked out to somewhere between 1/8 and a 1/10 of a unit of horsepower. Horsepower was based on the fact that the average brewery horse could move something weighing 330 pounds 100 feet in one minute, stop, and repeat for eight hours. And it would take about eight to 10 men to do the same, so your Camaro might have a 300 horsepower engine, but my Chevy Volt has like a 2000 manpower engine.

16. A Darwin is, naturally, a unit of measuring evolution.

We also measure things using the names of famous people. A Darwin, for instance, is a special ratio for measuring the rate of evolution. Evolution happening at the rate of one Darwin would change something by a factor of about 2.7 over a million years.

17. A Gal measures gravitational acceleration.

A Galileo or Gal is a unit of measurement used by physicists to talk about gravitational acceleration, but because there's only about a seven Galileo difference between the lowest and highest possible measurements on Earth, calculations are usually done in milli-Galileos.

18. Movements of your computer mouse are measured in Mickeys.

There's another guy you might have heard of who gave his name to a unit of measurement having to do with your computer mouse. The smallest detectable movement of a computer mouse—somewhere around 1/10 of a millimeter—is called a Mickey.

19. A Half-million twitter followers is a wheaton.

After half a million people followed Wil Wheaton on Twitter, John Kovalic dubbed that number a Wheaton. The beloved actor and brewmaster got to about six Wheatons on the social site before deactivating his account in 2018.

20. The Length of a Beard-SEcond is in dispute.

Speaking of great men with facial hair, a beard-second is the average length a man's beard grows in one second, but beard growth experts disagree on what that length actually is. Some say it's 10 nanometers. Some say it's five. Some say, "I can't believe that we're spending our time talking about this."

21. A millihelen is 1/1000th of one helen of troy.

Helen of Troy's magnificent mug is said to have launched a thousand ships, but what if there's just one ship that needs help getting out of port? Then, you need a millihelen, the amount of beauty required to launch a single ship.

22. A barleycorn is 1/3 of an inch.

A few hundred years ago in England, small objects were measured in barleycorns, as in grains of barley. A barleycorn was a third of an inch, which means it's barley there at all.

23. A poppyseed is even smaller.

If you needed something smaller than that, you could measure by poppyseeds, defined as either 1/4 or 1/5 of a barleycorn. In fact, grain is the basis of our whole system of terms for measuring weight.

24. A pound was 5400 or 6750 grains.

The Roman forerunner to the pound was the libra, which is why the lb. abbreviation stuck. Medieval England takes credit for using a pound (5400 grains) to measure metals and a mercantile pound (6750 grains) for goods.

25. A Bushel changes depending on the foodstuff.

The USDA has assigned individual bushel measurements to different things we grow in the ground. A bushel of corn is 56 pounds, while a bushel of oats is 32 pounds.

26. A Span is 9 inches.

A span isn't just a vague term for how long something is, like a bridge or wings or the length of time you can pay attention to something. It originally meant a distance of about 9 inches, or the width of a man's hand with the fingers out.

27. A Hand is now 4 inches.

Besides the span, we also have the hand, now mostly used for measuring horse height. It's the width of your hand with the fingers closed. But these days, it just means 4 inches no matter how gigantic your hands are.

28. A Finger is the width of your finger.

Noah Webster measured the breadth of a finger and nailed it down as 3/4 of an inch, but finger has been used a lot as a unit of measurement. Thus, it's not always clear whether we're talking about the width of the finger, like when your bartender pours you two fingers of booze.

29. A Finger can also be 4.5 inches of cloth.

This unit uses the length of a finger as the basis.

30. A Nail is 1/16 of a yard.

A nail of cloth, which is based on the length of your finger from the nail to the second joint, is half a finger, or 2.25 inches. That's also 1/16 of a yard.

So, there you have it. There are about seven barleycorns in a nail, two nails in a finger, four fingers on your hand, and three hands in a foot.

31. A Centipawn measures the value of chess positions.

And now let us discuss centipawns. Chess computer programs can evaluate the value of a particular piece or position in terms of hundredths of a pawn, or centipawns.

32. A Frigorie is a Calorie's nemesis.

You've heard of the boring old calorie, a unit that measures energy that produces heat. A Big Mac, for instance, has 550 of them. But, what about the energy to cool something? That unit of refrigeration is called a frigorie, which fell out of use in the 1970s.

33. An Oxgang is about 15 acres.

Also lost to history is the oxgang, a unit for measuring the area of land approximately equivalent to 15 acres—or the amount of land that a farmer could plow with an ox in one season.

34. An Olf is a unit of odor.

Luckily, we've still got the melodious olf. Olfs are used for measuring the air quality of indoor spaces, like offices. One olf is basically the amount of odor of one standard person. So, what's a standard person? The olf standard is a person with a skin area of 1.8 square meters, who bathes 0.7 times per day, and is seated comfortably in a comfortable temperature. If the person becomes slightly active, it rises to 5 olfs. A heavy smoker gives off 25 olfs while smoking and six while not.

35. A QuasiHemidemisemiquaver is a unit of brief musical time.

Also known as the 128th note, it lasts for 1/128 of a note. Nice how that works. Beethoven and Bach were fans.

36. You can cut the Quasihemidemisemiquaver in half.

The great news about music is that you can always go smaller: a demisemihemidemisemiquaver is a 256th note, and it's been used in works by Beethoven and Mozart. 

In this episode, John Green explains some offbeat units of measurement. You'll be measuring things by fingers in a jiffy.

8 Things That Happened on Leap Day

On Leap Day in 1692, the first warrants were issued in the Salem Witch Trials.

Since Leap Day comes just once every four years, events that happen on February 29 are somewhat rare. Check out these eight events that are extra memorable thanks to their timing.

1. On Leap Day in 1940, Hattie McDaniel won an Academy Award.

Actress Hattie McDaniel took home an Oscar for Best Supporting Actress at the 1940 Academy Awards for her role as Mammy in Gone with the Wind. The win made her the first African American to receive the award.

2. Buddy Holly’s lost glasses were found on Leap Day in 1959.

The singer's famous glasses disappeared for more than two decades after he died in a plane crash near Clear Lake, Iowa, in 1959. Holly’s trademark frames, along with the Big Bopper’s watch, were thrown clear of the plane wreckage. The items remained buried in the snow until the spring thaw, when they were turned over to the County Sheriff’s office and filed away in a sealed manila envelope, where they were forgotten. The envelope was rediscovered in 1980 by County Sheriff Jerry Allen, who came across it while looking for old court records. The discovery was announced on February 29, 1980. The glasses were returned to Holly’s widow, Maria Elena.

3. The Henriksen siblings—all of them—were born on Leap Day.

On February 29, 1960, Heidi Henriksen was born. Her brother, Olav, joined the family exactly four years later. And in 1968, to the day, Leif-Martin Henriksen entered the world. The Norwegian siblings held the Guinness record for most babies born on a Leap Day until 2012, when the Estes family from Utah tied them: Xavier Estes was born on February 29, 2004; Remington Estes in 2008; and Jade Estes in 2012.

4. Davy Jones died on Leap Day in 2012.

In 2012, the Monkee passed away after suffering a heart attack. He was just 66, leaving many fans in shock at his unexpected death.

5. Hank Aaron became the highest-paid Major League Baseball Player on Leap Day.

A $200,000-a-year contract might seem like peanuts for a MLB player today, but by 1972 standards, it was a big deal. So big, in fact, that the three-year contract Aaron inked to play for the Atlanta Braves made him the highest paid baseball player in the league.

6. The future Pope John Paul II was nearly killed on Leap Day.

Back when he was just 24-year-old Karol Wojtyla, Pope John Paul II was walking home when a German army truck hit him and left him on the road for dead. The driver of a lumber truck picked him up and took him to the hospital, where Wojtyla remained unconscious for nine hours. It’s said that the incident inspired him to switch to a spiritual career path.

7. Family Circus debuted on Leap Day in 1960.

On February 29, 1960, Bil Keane’s long-running comic strip debuted as The Family Circle. Inspired by Keane’s own wife and children, Family Circus is now drawn by Keane’s youngest son, Jeff—the inspiration for “Jeffy” in the comic strip.

8. The first warrants were issued in the Salem Witch Trials on Leap Day.

Salem residents Sarah Good, Sarah Osborne, and Tituba were accused of witchcraft on February 29, 1692. After refusing to confess, Good was hanged and Osborne died in prison; Tituba, a slave, admitted to her supposed crimes and was released from jail a year later.
