Risk-Free 100% Satisfaction
Costco allows members to return almost any product at any time if they are not satisfied. This "lifetime" policy is what makes Costco a fan favorite. No receipt is needed as long as you have your Membership Card.
The 90-Day Exception
Keep in mind that Major Appliances and Electronics (TVs, Computers, Cameras) must be returned within 90 days of purchase to qualify for a refund.
