I'd like to create a web store, but I can't find a provider with payment processing option included in the package. Like with Yahoo Merchant Account you can create a web store up to the payment processing segment. Then they offer you FirsData payment processing provider that you must buy separately from the Merchant Account solution. The problem is that payment processing providers charge a lot. Like Authorize.net charges you 100 usd monthly plus astronomical transaction fees. It doesn't pay off, you don't earn any money this way. Does anyone know for any merchant account web store provider that has payment processing option already included in the web store package? If not I'd like to know the cheapest and most simple solution for payment processing and how to integrate it into some web store or merchant account provider?
