PriceAdjustPro

Costco quietly drops prices after you buy — and gives you 30 days to claim the difference. Almost nobody does, because almost nobody notices.

PriceAdjustPro notices for you.

CONNECT ONCE, THEN FORGET IT
Link your Costco account and your receipts import themselves. No photographing, no typing, no filing.

EVERY REFUND YOU'RE OWED
We watch the price of everything you've bought. When one drops inside the 30-day window, you get the item, what you paid, what it costs now, and exactly how many days you have left to walk in and claim it.

KNOW WHAT GOES ON SALE NEXT
This month's coupon book and the next one, filtered to the things you actually buy.

THE .97 MARKDOWNS
A price ending in .97 means Costco is clearing an item that didn't sell. They never advertise these. We surface the ones other members have spotted, so you know what to look for before you go.

SEE WHERE THE MONEY WENT
Every trip, every category, every month, drawn from your own receipts. Scrub the chart to read any month.

YOUR RECEIPTS, KEPT
Searchable, itemised, and yours — including what each trip saved you.

Free through 2026. No ads. We don't sell your data.
