Google Extends Online Payment Options

I was mentioning Goggle Base before and I was thinking... If you post an article there and add a price for it, that means someone will be able to buy it. If user are able to buy that thing, it should be a way to process credit cards and financial info, and.. why use another existing tool / service for that and not build your own Online Payment System?
