Bumbei

Bumbei is a US-focused bitcoin cashback service that helps shoppers earn sats when they buy from participating online stores. With more than 90 stores listed, it lets customers start a purchase through Bumbei, then shop and check out as usual at the same price and with the same promotions. Once a store confirms a purchase, the cashback moves from pending to an approved balance.

Bumbei shares part of the commission it receives from stores with shoppers, and membership is free. Rewards are paid in bitcoin, with no points, expiration dates, withdrawal threshold, or fee deducted from the approved balance. Users can withdraw from as little as one sat to a Lightning Address or Lightning invoice; Bumbei says it covers the Lightning fee. The service also offers product links that can earn sats when someone makes a purchase through them. Customers can track purchases through pending, approved, and sent statuses, receive email updates, and report missing purchases for follow-up.
