Costco Return / Refund / Exchange Policies Synopsis. Costco has historically had one of the best return policies around. A while ago the policy was made more restrictive for electronics returns, as some customers had been taking advantage of the opportunity to return items long after purchase.
Also when I purchased the Costco Danby dehumidifier, $199.99 last month the salesperson said there was a 3 month return limit just like electronics as many people were buying in the summer and returning in the fall.
