Shopadar

Shopadar is a price comparison extension that searches multiple
online retailers simultaneously and displays results ranked from
lowest to highest price — so you can find the best deal without
opening multiple tabs.

HOW IT WORKS:
Type any product into the Shopadar popup and receive results from
major retailers ranked by price in seconds. Filter results by
free shipping, in-store pickup availability, new or used condition,
minimum rating, price range, and specific retailers.

FEATURES:
- Results ranked lowest price first across 10+ major retailers
- Filter by free shipping, pickup, condition, rating, and price range
- Price drop alerts: save a product and get notified when it drops
- Search history for quick access to recent searches
- Zero sponsored placements — rankings are purely by price
- Works for any product category

FREE PLAN: 10 searches per day with full filter access
PRO PLAN ($4.99/month): Unlimited searches, unlimited price alerts,
price history, and email notifications

SETUP: After installing, click the Shopadar icon and enter your
SerpAPI key in Settings for live results. A free SerpAPI key
(100 searches/month) is available at serpapi.com. The extension
also includes a demo mode with sample data to preview functionality.

Privacy: Shopadar activates only when clicked. No browsing history
is read or tracked.
