Price Drop Checker
Many stores refund the difference if a price falls soon after you buy. Log your purchases, see how many days each one has left, and get the exact request to make when the price drops.
Nothing to watch yet
Add something you bought recently. Check its price every few days until the window closes.
Add a purchase
Only add things you actually bought. Keep the receipt or order email, since the store will ask for it.
Store rules
How long each store gives you to ask for the difference. Checked against each store's own policy page in September 2026. Stores change their rules, often for sales, clearance and member-only prices, so confirm with the store before you count on a window. You can change any number here.

Add a store
Type the store name and tap "Find rules". With your Gemini key saved in Settings, the app looks up the store's price adjustment policy on its own website and shows you the source before adding it. You can also type the days yourself.

Optional: AI price lookup
"Look up price" asks Google Gemini, with Google Search, for the store's current price and shows its sources. It uses your own key from aistudio.google.com/apikey, stored only in this browser. AI can be wrong, so always open the source and confirm the price before claiming.
