Why Costco's Return Policy Stands Out
Costco's return policy is built on a simple principle: Risk-Free 100% Satisfaction Guarantee. This applies to both your membership and the products you buy. If you're not satisfied with something, Costco will refund your purchase — no questions asked, no time limit (for most items).
This policy is more generous than virtually any other major retailer. While competitors like Walmart give you 90 days, Target gives you 90 days, and Best Buy gives you 15 days, Costco says "bring it back whenever." It's a powerful reason people stay loyal to their membership.

Electronics 90-Day Policy: What You Need to Know
Costco introduced the 90-day electronics window because of return abuse — members were returning TVs after the Super Bowl, computers after finishing a project, or cameras after a vacation. The 90-day limit strikes a balance: generous enough to truly evaluate a product, but not so open-ended that people treat it as a free rental service.
The 90-day clock starts from the date you received the merchandise, not the purchase date:
- In-store purchases: day you brought it home
- Online/delivery orders: delivery date
- Pre-orders: day the item ships and tracking begins
💡 Pro Tip: Tech Support First
Before returning electronics, contact Costco Concierge Services — a free technical support line available for many electronics. They can troubleshoot issues, help with setup, and sometimes resolve problems without needing a return. This extends the value of your purchase.
Returns Without a Receipt
One of the best parts of Costco's return policy: you don't need a receipt. Every purchase is linked to your membership number, so Costco can look up your entire purchase history electronically.
Just bring:
- The item you want to return
- Your Costco membership card
That's it. The returns desk scans your card, finds the purchase, and processes the refund to your original payment method. For online orders, log into your account and you'll see your full order history with return options.
How Costco Compares to Competitors
