There are some merchant accounts that work with one shopping cart, and some that work with others. Who wants to cycle through software trying to find a checkout system for their customers when they can have it all in one convenient package? If you need to accept payments online, then you should be using the Yahoo Stores Merchant Account as a companion to your Yahoo Store. A Yahoo Stores Merchant Account will work directly with your Yahoo Store site to allow you to process credit and debit cards immediately after setup. The customer will appreciate the ease with which they can check out of your store and move on with their browsing. Nobody likes to be redirected over and over with cumbersome and temperamental shopping cart systems, so give your customers the comfort of a name like Yahoo.
