Costco’s famously generous return policy is one of the many reasons members stay loyal to the warehouse giant. While this policy provides peace of mind for shoppers, certain food items consistently find their way back to the return counter more often than others. Understanding which products are frequently returned can help you make informed decisions during your next shopping trip.
Fresh produce problems and proper storage
Fresh produce tops the list of returned items at Costco, with spinach and berries being particularly problematic. The bulk packaging that makes Costco famous can work against these perishable items, as they often spoil before families can consume them entirely. Many customers report finding soggy greens or moldy berries shortly after purchase.
To maximize the life of your produce, consider splitting large packages with another household or immediately freezing portions you won’t use within a few days. Store berries unwashed and only rinse them right before consumption.
Meat storage mishaps and spoilage concerns
Both chicken breasts and red meat make frequent appearances at the returns counter. The journey from processing facility to store can impact these proteins’ shelf life. When returning spoiled meat, Costco recommends freezing it first and bringing it to the original purchase location.
Consider portioning and freezing meat immediately after purchase. Write the date on freezer bags and organize your freezer so older packages get used first.
Something fishy about seafood returns
Seafood, especially salmon, ranks high among returned items. Even before the sell-by date, some customers report their fish developing an off-putting smell. What if you could eliminate this risk? Many experienced Costco shoppers suggest checking the packaging date and opting for frozen seafood instead of fresh when possible.
When selecting fresh fish, examine the flesh closely for any discoloration and check that the package feels cold to the touch. Transport it in an insulated bag and refrigerate immediately upon arriving home.
Nuts and protein bars storage requirements
The high oil content in nuts makes them susceptible to turning rancid, especially in warm storage conditions. Similarly, protein bars often come back to stores due to texture changes or expired dates. Store nuts in airtight containers in your refrigerator to extend their shelf life.
Before purchasing protein bars in bulk, try a smaller package from another retailer to ensure you enjoy the flavor and your body tolerates the ingredients well.
Bulk alcohol purchases and temperature changes
Surprisingly, alcohol makes frequent appearances at the returns counter, though usually unopened. Many returns occur after events where less was consumed than anticipated. However, store employees note that temperature fluctuations during transport and storage can affect the taste of returned bottles.
When planning event purchases, consider Costco’s unit prices versus smaller quantities from local stores. Factor in storage space and temperature control capabilities before making bulk alcohol purchases.
Dairy product dates and packaging integrity
Milk and yogurt returns often stem from leaking containers or early spoilage. Check the seal integrity of milk jugs and examine yogurt packaging for any bulging or damage before purchase. When possible, select containers from the middle or back of the refrigerated section, where temperatures tend to be more consistent.
For yogurt specifically, check the sell-by dates and avoid packages with excessive liquid on top, which might indicate temperature fluctuations during transport.
Bread preservation and mold prevention
While Costco’s bread prices are attractive, the large quantities can lead to waste and returns due to mold growth. Consider your household’s consumption rate and freezer space before purchasing multiple loaves. Bread freezes well when properly wrapped, and you can thaw slices as needed.
Store bread in a cool, dry place and never refrigerate it, as this actually accelerates staling. Remember that warm, humid environments promote mold growth, so proper storage is essential.
Understanding these common return patterns can help you shop more strategically at Costco. Remember that while their return policy is generous, proper storage and realistic purchasing quantities are key to reducing food waste and maximizing your warehouse shopping experience.
