MasterCard Marketplace
MasterCard is one the biggest processors of payments between merchants and the banks or credit unions who issue credit and debit cards. And while MasterCard doesn't issue its own credit cards, they do offer holders of MasterCard-branded cards a smart way to earn discounts and cash back for online shopping, with the MasterCard MarketPlace. The MarketPlace offers hundreds of tailored discount offers each week, based on members' merchant preferences. These offers span more than 25,000 participating merchants nationwide in 19 categories-from entertainment to travel, computers, electronics, apparel, and more.
