While most items can be returned to a Costco without hassle, certain products are strictly off-limits for returns...

Cigarettes and alcohol top the non-returnable list due to legal restrictions. Once purchased, these items cannot be brought back under any circumstances.

Special-order kiosk items like custom photo books or personalized products are final sales. Since these are made specifically for you, Costco cannot resell them to other customers.

Diamonds over 1.00 carat must be returned within 48 hours. After this brief window, these precious stones become permanent purchases, so inspect carefully before leaving the store.

Airline tickets and vacation packages are non-refundable through Costco Travel, though you may work directly with airlines or hotels depending on their individual policies.

Gift cards cannot be returned once purchased, as they're considered cash equivalents and subject to different regulations.

Digital downloads and streaming services are final once accessed or activated, similar to most retailers' policies on electronic media.

Tires have specific warranty terms rather than Costco's standard return policy, with road hazard coverage lasting five years.

Major appliances installed in your home have limited return windows and may require manufacturer warranty claims instead.

Electronics now have a 90-day return policy rather than the unlimited window, marking a significant policy change.

Opened software cannot be returned due to licensing agreements and piracy concerns.
Understanding these exceptions helps you shop smarter at Costco while still enjoying one of retail's most customer-friendly policies.
