Fairprice 作成者: BuildMidas

Fairprice turns any shopping site into a smarter buying decision. It tracks the price of what you're looking at, shows you how that price has moved over time, and surfaces the coupon codes you've saved — right on the product page, exactly when you need them.

WHAT IT DOES
- Track the price of any product on any shopping site with one click
- See a clear price-history chart, so you know whether today's price is actually a good deal
- Save coupon codes once and have Fairprice surface them on matching stores automatically
- Spot price drops at a glance instead of checking back manually
- Keep everything in a personal, on-device library you fully control

HOW IT WORKS
Open a product page, click Fairprice, and it starts tracking that item's price. Come back any time to see the price history. Paste in coupon codes you've collected, and Fairprice reminds you of them the next time you're on that store — no more forgotten codes at checkout.

PRIVATE BY DESIGN
Fairprice makes zero network requests — every price you track, chart you view, and coupon you save stays stored locally in your browser. There's no account, no sync server, and nothing is ever sent anywhere.
