Capital One Shopping
visit →Save with your daily offers!
Capital One Shopping is a consumer-side browser extension that auto-applies coupon codes at checkout, surfaces lower prices from competing retailers, and tracks price drops on items shoppers have viewed or bought. For ecommerce operators, it sits on the demand side rather than the merchant stack — meaning brands encounter it as a price-comparison and coupon layer affecting cart conversion and margin, not as a tool they license or deploy themselves.

- Applies coupon codes automatically at checkout across participating retailers
- Compares prices against competing sellers during the shopping session
