Deal Sniffer is a browser extension that notifies you whether cashback reward incentives exist for a merchant when shopping online.

For example, let’s suppose that you’re browsing your favorite online store (i.e., Amazon, Microsoft Store, Reebok, etc.). Well, if a cashback rewards incentive exists for that online store, Deal Sniffer will notify you with all that information, such as the applicable rebates and the cashback provider.
