About
Paribus, rebranded as Capital One Shopping, is a free browser extension designed to help everyday shoppers save money without any extra effort. Once installed, it automatically scans for available coupons and promo codes and applies the best ones directly to your cart at checkout.

Compatible with all major browsers, Capital One Shopping is one of the most comprehensive shopping assistant tools available, combining price intelligence, coupon automation, and deal discovery in a single lightweight extension.
