Costco return policy
Costco.com orders can be adjusted within 30 days (Order History > Price Adjustment). Warehouse purchases can't use online prices, but warehouses often adjust within 30 days if the shelf price drops: ask at the membership counter. Special-event and limited-quantity pricing may be refused.

What the law gives you in the United States
No nationwide return or price-adjustment right: in the US each store sets its own rules, so Pricemend goes by the store's published policy.
This applies on top of whatever Costco offers, and sometimes gives you more.
Bought something and it is cheaper now?
Pricemend reads your receipt, works out your last day to act, and tells you when a price drops.
