Group Buyer is a free lifestyle app developed by GroupBuyer for Android users. The app offers a unique shopping experience with a GroupDollar rebate campaign that allows users to earn extra bonuses by inviting friends to shop using the app.

To participate in the campaign, users need to have a VISA or Master Credit Card and invite friends to join their friend circle. By doing so, users can earn GroupDollars that can be redeemed as a rebate on their purchases. The more friends users invite, the more GroupDollars they can earn.

The app also allows users to make payments through the mobile app, earning them additional GroupDollar bonuses. With Group Buyer, users can enjoy a rewarding shopping experience with their friends and family, all while earning extra savings.
