Take Advantage of Sale Prices After You’ve Made a Purchase
Although the returns line at Costco can be one of the busiest places in the store, you can return items that you bought for full price to the store to take advantage of deals that you weren’t aware of when you made your purchase. As long as you bring the item in within 30 days of your purchase, you can utilize Costco’s price adjustment policy to lower the cost of your purchases significantly.
