If you bought something at full price within 30 days before it went on sale, Costco's price adjustment lets you ask for the difference back. This adds up fastest on big-ticket items — a $300-off soundbar bought two weeks ago could mean up to $300 back, if it's still at the sale price when you ask. Costco can decline.
