When you order custom-made items like personalized jewelry or specially crafted furniture, they’re tailored just for you. According to Costco’s return policy, customized items are non-returnable because they can’t be resold. It’s a bit like getting a customized pizza; once it’s made, it’s yours to enjoy. So, double-check every detail before confirming your order!
Alcohol

Due to legal restrictions in several states, returning alcohol to Costco can be tricky or downright impossible. Each state’s laws dictate the return policies on alcohol, so it’s best to be sure before you buy that extra-large bottle of wine. Costco clearly states this policy aims to comply with state regulations—no surprises at checkout!
Cigarettes

Cigarettes fall under a similar umbrella as alcohol due to state-specific laws that prevent the return of tobacco products. If you’re contemplating quitting, accidentally buying a whole carton could be your unexpected motivator. Remember, once they’re purchased, they’re yours.
Diamonds Over 1 Carat

Costco provides a verification process for returning diamonds over 1 carat, which involves a thorough check to ensure the diamond matches the one sold. This high-value transaction is carefully controlled to prevent fraud, making returns more complex than usual. Before purchasing that eye-catching stone, be sure it’s the gem you want.
Electronics After 90 Days

Costco allows electronics to be returned within a 90-day window. After that, your tech purchases are final. This period gives you ample time to assess your gadgets—consider it a 90-day trial. It might be time to part ways if your new electronic doesn’t spark joy by day 89.
Tires That Have Been Installed

Batteries

Used batteries are not returnable because their capacity diminishes with use. Just like a cup of coffee, once it’s consumed, it’s gone. Costco’s policy reflects a general retail standard, ensuring customers receive only new, fully charged batteries.
Special Event Tickets

Perishables and seasonal goods are on a no-return list due to their nature. Whether it’s festive decorations or fresh produce, once these items leave the store, they’re meant to be used promptly. It’s a way to ensure quality and safety for all customers.
Opened Software or Video Games

If you open software or video games, you can’t return them to Costco. This policy helps protect against software piracy and ensures that all customers receive brand-new products. Always read reviews and system requirements before tearing off the shrink wrap!

Custom optical products, like glasses or contacts, are made to your specifications and thus aren’t returnable. It’s crucial to ensure your prescription is accurate before ordering—consider it customizing your view of the world.
Gift Cards

Once purchased, gift cards are considered spent. They are non-returnable and non-refundable, much like cash. This is a common practice in many retail settings, not just Costco. So, think of gift cards as a commitment to spend by you or the lucky recipient.
