As per Costco's policy, customers are eligible for a refund if the price of a purchased item decreases (within one month). We've developed a simple app to know when price drops.
Our app relies on prices from Costco's website, but not all items purchased from warehouses are available there. We're thinking of crowdsourcing to find the latest prices but its still work in progress. If you're a Costco member, please try this app and share your feedback.
