Dave Ramsey warns shoppers to never buy these Costco items

Costco has built a loyal following by offering warehouse-sized packages at prices that typically beat traditional grocery stores. For many families, a membership pays for itself through great Costco hacks like lower prices on household essentials, gas, and pantry staples. Financial expert Dave Ramsey doesn't argue with that idea. Instead, he draws a distinction between shopping strategically and simply buying more because the price looks attractive.

That distinction matters more than ever. Bank of America estimates that nearly one in four consumers is living paycheck to paycheck, while Americans collectively carry more than $1.2 trillion in credit card debt. In that environment, even small impulse purchases add up. Ramsey wants to inform people that buying in bulk only causes real savings if everything you purchase actually gets used. Before loading the cart, he suggests thinking beyond the price tag and focusing on long-term value.

Editor's note: Consumer debt figures are based on Federal Reserve data, while paycheck-to-paycheck estimates come from Bank of America research. Prices and product availability at Costco may vary by location.

1. Fresh produce

Ramsey singled out fresh fruits and vegetables as one of the riskiest warehouse purchases. He warns that, "buying perishable items like produce in bulk is always a huge gamble. The odds are rarely ever in your favor."

Large containers of lettuce, berries, bananas, or salad mixes seem like incredible deals. However, if even part of the package spoils before it's eaten, the lower price per pound becomes meaningless.

2. Dairy Products

Milk, yogurt, cheese, and other refrigerated dairy items sell for low prices at Costco. But Ramsey suggests looking beyond the sticker price and considering how quickly these products get used in your household.

A family with young children might finish oversized containers before expiration, while a couple or individual could struggle to do the same. Throwing away expired food effectively erases any savings that you thought you were getting.

3. Bakery Items

Costco's bakery is known for oversized muffins, pastries, cookies, and cakes. While the cost per item is reasonably low, the quantity could become the bigger issue.

Unless you're buying for a gathering or planning to freeze portions immediately, bakery products tend to lose freshness within days. Ramsey recommends avoiding purchases that you will throw away portions of simply because they seemed like a bargain at the moment.

4. Pre-cut fruits and vegetables

Convenience foods are another category Ramsey approaches cautiously. Pre-cut fruit trays, sliced vegetables, and ready-to-eat produce are great time savers, but they're also more likely to go bad quickly.

Because these products have already been cut and prepared, they generally have shorter shelf lives than whole produce. If meal plans change or leftovers pile up, some pre-cut fruits and vegetables may end up in the trash instead of on the dinner table.

5. Spices

Warehouse-sized spice containers look like smart purchases because dried seasonings don't technically spoil for years. Ramsey's concern with this isn't food safety, it's value.

Most home cooks use relatively small amounts of spices. Long before a giant container is empty, many seasonings begin losing their flavor and aroma. Paying less per ounce means little if much of the spices don't work the way they are supposed to in your meals.

6. Condiments

Large bottles of ketchup, mustard, mayonnaise, barbecue sauce, and salad dressing also deserve a second look. Many families simply don't go through these products quickly enough to warrant a bulk purchase.

Even after opening, condiments gradually lose quality over time. Buying the largest container available may feel economical, but replacing half-used bottles months later is not helping you save anything, according to Ramsey.

7. Limited-time "treasure hunt" items

One of Costco's biggest draws is its constantly changing selection of seasonal and limited-time merchandise. Ramsey believes this "treasure hunt" experience is exactly where many shoppers overspend.

Unique kitchen gadgets, decorative home goods, specialty foods, and unexpected deals create a sense of urgency. Because inventory changes frequently, shoppers can feel pressure to buy immediately rather than think through whether the purchase truly fits their budget.

8. Purchases outside your regular routine

Ramsey recommends asking one simple question before buying any item that isn't already part of your normal shopping routine, "Do I use this consistently?"

If the answer is no, he suggests leaving it behind. A discounted product that sits untouched in the pantry or closet is no longer a bargain.

9. Bulk pantry staples from Costco still make sense

Ramsey's advice isn't about avoiding Costco altogether. In fact, he points to non-perishable staples as examples of smart warehouse purchases.

Dry pasta, rice, canned vegetables, canned beans, oats, flour, sugar, and similar shelf-stable foods typically store well for long periods. When purchased in quantities a household realistically uses, these products are great ways to save without creating unnecessary waste.

10. Paper products and household essentials

Paper towels, toilet paper, tissues, trash bags, laundry detergent, and other household necessities also fit Ramsey's definition of sensible bulk purchases.

These items don't spoil, they're used regularly in most homes, and purchasing larger quantities typically has a lower cost per unit. As long as you have adequate storage space and avoid buying more than your household realistically needs, these purchases are good with Ramsey's overall approach to saving money.

11. Shop with a list and stick to it

Ramsey's most practical Costco advice has nothing to do with any specific product. Instead, it focuses on shopping habits.

Costco's warehouse layout is intentionally designed to make shoppers wander. Shoppers walk past hundreds of tempting displays before reaching many everyday essentials. Bringing a written shopping list, and resisting the urge to deviate from it, helps counter that strategy while helping you stick to your budget.

Bottom line

Dave Ramsey isn't suggesting shoppers cancel their Costco memberships or avoid warehouse clubs entirely. His message is meant to show people that bulk buying only creates savings when products actually get used. If food spoils, condiments expire, or impulse purchases collect dust, you don't actually save money on groceries.

One additional habit to consider is shopping after checking your pantry, refrigerator, and freezer. Taking a quick inventory before leaving home reduces duplicate purchases, encourages using what you already own, and makes it easier to recognize real deals instead of simply filling a larger shopping cart.
