The average American family spends $4,000 per year (about $333 per month) on groceries, according to the Bureau of Labor Statistics. But for many, food eats up even more of the household budget due to shopping mistakes.
Bad shopping habits are one reason the average U.S. household throws away $640 worth of food every year, according to the American Chemistry Council. And that just counts the soured milk and moldy peaches we get rid of. Americans waste even more money by buying overpriced items, ignoring sales, and not using coupons, according to consumer experts.
Let’s look at ways you likely waste money at the grocery store, including the worst day of the week to shop and what you’re missing right in front of you.
1. Not making a list
Grocery shopping without a list is one of the biggest mistakes you can make. “If you go into the grocery store without a plan, you’re more likely to walk out with items you wouldn’t otherwise purchase,” Kendal Perez of Coupon Sherpa told The Cheat Sheet. If a paper list is too much trouble, try apps, such as Out of Milk and Grocery IQ, which make it easier to track what you need and locate deals. The latter is key to saving even more money.
“Your grocery list should be composed of products featured in the store’s weekly sales ad,” Perez said. “Planning meals around what’s on sale is key to saving money on food and reducing your overall grocery budget.”
Next: This mistake is not only a waste of money, but also a waste of time.
2. Hitting every aisle
A slow, methodical trek through the grocery store can backfire if you’re not careful. “Don’t go down an aisle where you don’t need anything — it can only lead to overbuying,” said David Bakke, a consumer expert with Money Crashers.
Instead, review your shopping list. Then bypass any part of the supermarket that doesn’t have items you need. You’re less likely to fill your cart with chips or expensive frozen meals if you don’t walk past them in the first place.
Next: Bulk isn’t always cost-effective.
3. Always buying in bulk
“Buy 10 and save” deals are tempting, but stocking up on large quantities of an item or automatically reaching for the bigger container isn’t always a savvy move.
“Buying in bulk can be a money saver as long as you’ll use the item before it expires. Buying 100 ounces of ketchup at once might backfire on you,” Bakke said. For reference, an opened container of ketchup is good for four to six months, according to Real Simple. After that, it might taste a bit off.
Next: Price varies.
4. Only shopping at one store
“Loyalty to just one store will cost you in most cases,” Perez said. So it’s best to shop around. For Perez, that means hitting a warehouse club, such as Costco, which has good deals on usually pricey items, including maple syrup, butter, and avocado oil. Walmart is her go-to for household items, such as toiletries. And Sprouts is where she shops for produce.
“Knowing which stores have the best prices on the items you buy is key to saving money on groceries,” consumer expert Andrea Woroch said. “Personal-care products, for example, are almost always better priced at Walmart or Target compared to grocery stores, while drugstores often have big savings on cereal when you include their loyalty program discounts. By conducting a bit of research on who has the best prices for the products you buy most, you can cut your grocery bill significantly.”
Next: Store brands might be even better — and cheaper — than name brands.
5. Passing on the store brands
Only buying name-brand products is a surefire way to run up your grocery bill if you’re not careful. “Try the store brands of your favorite items. It’s not like when we were kids and the ‘generic’ brands were all horrible quality,” said Ken Immer, the President and Chief Culinary Officer of Culinary Health Solutions.
“Many name brands are actually packing their same products under store labels with the same quality standards and a lower price,” he added. If a generic product’s packaging looks similar to the name-brand, that’s a good sign it’s made by the same manufacturer, Immer said. If you can’t bring yourself to give up your name-brand favorites, keep an eye out for coupons to help you save.
Next: Look up — and down.
6. Only shopping at eye level
Grabbing the first package of coffee or box of cereal you see is a mistake, consumer experts say. Stores put the pricier items at eye level so you’ll grab them without scanning the shelves for a better deal. The same goes for end-caps, or the displays at the end of the aisle.
“The best bargains are closest to the floor, so get your exercise and bend down,” said Jamie Novak, author of Stop Throwing Money Away. “Cheaper items are always farthest right on the shelf, so keep going down the aisle until you get to the end.”

7. Not shopping the sales cycles
You know canned pumpkin will be on sale in the fall, and chocolate is cheaper around Valentine’s Day. But those aren’t the only seasonal sales. “There are a lot of other seasonal items that go on sale during months you may not expect, like oatmeal in January, sodas in July, and peanut butter in September,” said Nedalee Thomas, a frugal-living expert and founder of Princess Power.
Stores also mark down items every six to 12 weeks as they restock shelves, Thomas explained. Every item has a cycle. And by tracking the prices of the items you buy most frequently, you can identify the weeks when your favorite foods will be on sale and plan to stock up . “With some time and practice, you can learn how to keep tabs on the best deals,” Thomas said.
Next: You’re not done once you hit the checkout line.
8. Not paying attention at the register
Mistakes can happen when cashiers scan the items in your cart. Big-box store Target was recently ordered to pay a $4 million fine after an investigation revealed items sometimes rang up at higher-than-advertised prices.
“Watch as your items are rung up,” Novak said. “Overly sensitive pricing guns can inadvertently scan an item twice. A cashier can accidentally charge you for expensive curly parsley when what’s really in the bag is the less expensive flat leaf parsley.”

9. Shopping on the wrong day of the week
Time your shopping to coincide with your store’s weekly sales. Often, these kick off on Wednesday and may overlap with the previous week’s deals, so you can double up on bargains. Shopping on the day the sale starts ensures you can snag any bargains before products sell out. If an item you want is out of stock, ask for a rain check, Perez advised.
One of the worst days to shop is Sunday, according to an analysis by mobile shopping app Ibotta. Ice cream, snacks, and cleaning products are all more expensive at the start of the week, its analysis found.
Next: Time matters.
10. Shopping at the wrong time of day
Head to the supermarket just before closing to snap up deals on soon-to-be-discarded items. “If you go at the end of the day, you can oftentimes find manager’s specials on meats — buy one get one free, 50% off, et cetera,” Durkin said. Fill your freezer with the discounted meats, and you can eat well for a fraction of what you’d normally pay.
Next: Do you need food now? Don’t go grocery shopping.
11. Shopping while hungry
You probably know shopping when you’re hungry or stressed is bad. You’re more likely to fill your cart with impulse purchases. Plus, crowded stores lead to a “get in and get out” attitude, which “leaves little time for comparing prices or checking store apps for digital coupons,” Perez said.
Next: Save those receipts.
12. Throwing away your receipts
You probably just leave your grocery receipt crumpled at the bottom of a bag. It’s rare that you return a purchase, so why bother with the receipt, right? What if it could save you thousands of dollars? Personal finance blogger Karen Cordaway says you can save $2,200 or more per year simply by taping your grocery receipt to the fridge. This trick helps you eat food before it goes bad, and it’s a good reminder that any food you do waste has a price.
“Refer to the receipt when you use the fridge because it will remind you of what you bought, and when you purchased it,” she writes. “That receipt is marked with all of the items you just purchased in a list format — and it’s dated so you’ll know exactly when you purchased everything.”
Next: A little prep works goes a long way toward savings.
13. Not prepping food
Just like preparing a list is essential so is prepping food. Prepping meals, or even just ingredients for meals, translates to grocery savings. You can take advantage of bulk savings, knowing you’ll turn those ingredients into your lunches for the week. Plus, having meals on hand means less of a chance for impulse buys later on.
Next: Your fear of new foods could cost you.
14. Getting stuck in a food rut
Not an adventurous eater? Is your grocery list pretty much the same each week? Then, you’re definitely not always getting your favorite foods at a sale price. Instead of picking up a grapefruit, for instance, every time you visit the store, try to limit yourself to when it’s in season — and cheaper — during the winter months. Branch out to similar foods on sale. Your taste buds may not care, but your wallet will thank you.
Next: Never wonder whether you already have something at home.
15. Stuffing your fridge and pantry
Most people visit the grocery store on a pretty regular schedule. But they don’t often decide whether they even need more food. Instead of coming to a standstill in a grocery aisle, trying to remember whether you already bought a bottle of ketchup last week, take inventory of what you have before you go. If it looks like you’re stockpiling food for an apocalypse, take a week off grocery shopping, eat what you have, and save money.
