Costco's return policy is legendary — no time limit on most items, no questions asked. But there are important exceptions and strategies that can save you time and hassle. Here's everything you need to know.

Costco Return Policy Overview

No Time Limit Items

Most Costco purchases can be returned at any time for a full refund:

  • Clothing and shoes
  • Furniture and home goods
  • Toys and books
  • Kitchen appliances (small)
  • Food and beverages (even if partially consumed)
  • Cleaning supplies
  • Personal care products

90-Day Return Items

  • TVs and projectors
  • Computers and tablets
  • Cameras and camcorders
  • Smartphones (carrier-activated)
  • Smart watches
  • Major appliances (refrigerators, washers, dryers, ranges)

Non-Returnable Items

  • Cigarettes and alcohol (where prohibited by law)
  • Custom products (special-order items)
  • Airline and event tickets
  • Gold bars and coins

Special Categories

  • Diamonds over 1 carat: Returnable with original paperwork and IGI inspection
  • Tires: Must be returned to the Tire Center
  • Hearing aids: 180-day return window
  • Optical: Satisfaction guaranteed, but prescription adjustments may be needed

How to Return to Costco

In-Store Returns

  1. Bring the item to the Returns counter (no receipt needed)
  2. Costco looks up your purchase through your membership number
  3. Refund processes immediately to original payment method
  4. If paid with Costco credit card, refund goes back to card

Online Returns

  1. Log into costco.com > Orders & Returns
  2. Select the item and click "Return Item"
  3. Print the prepaid shipping label
  4. Ship the item back
  5. Refund processes within 5-7 business days after receipt

Costco Concierge Services (Electronics)

For electronics and tech products, Costco Concierge provides:

  • Free technical support: Help setting up and troubleshooting
  • Extended warranty: Costco adds 2 years to the manufacturer warranty (on top of credit card extensions)
  • 90-day return window: More generous than most retailers

Tips for Costco Returns

  • No receipt needed: Your membership number tracks all purchases
  • Bulk returns are fine: Costco doesn't penalize for returning part of a bulk pack
  • Food returns accepted: If you didn't like the taste or it spoiled too quickly, bring it back
  • Membership cancellation refund: If you cancel your membership, Costco refunds the membership fee at any point during the year

Quick Checklist

  • [ ] Check if your item falls in the 90-day electronics/appliance category
  • [ ] No receipt needed — just your membership card
  • [ ] Return in-store for immediate refund
  • [ ] For online purchases, start return at costco.com
  • [ ] Take advantage of the free 2-year warranty extension on electronics
  • [ ] Don't hesitate to return food or household items you're unsatisfied with

Bottom Line

Costco's return policy is the most generous in retail. The no-time-limit policy on most items, combined with the automatic 2-year warranty extension on electronics, makes Costco purchases essentially risk-free. Always buy electronics at Costco when possible — the warranty extension alone is worth the membership fee.
