CostChirp app · In development
Check for price drops after you buy
Keep an eye on prices after checkout. The CostChirp app is being developed to help you check later prices and follow Costco’s price adjustment process.
How the app will work
Start with your purchase details. Then check whether a later price applies to the same item and purchase channel.
01 · Review
Confirm your purchase
Capture and review purchase details in the app. Check the item number, pack, amount, purchase date and channel before saving.
02 · Compare
Check a later price
Check later prices for the same item, pack and purchase channel.
03 · Request
Follow Costco’s instructions
See the potential difference and check the conditions, then follow Costco’s official request process.
Release status
The app is in development and is not available to download yet. Purchase tracking will require an account and Premium access; pricing and release availability are not announced here.
Your purchase records stay private
You’ll capture and review receipts in the phone app. The website does not accept receipt photos or receipt entry. Public product history is separate from private purchase records.
Costco makes the final decision
Eligibility depends on when and where you bought the item and Costco’s current policy. CostChirp won’t submit requests for you or guarantee a refund.
You can browse sale history on the website for free while the app is in development.
