I'm going to be creating a site for a business with the following: Single Item purchases with Paypal, Google Checkout and Amazon Checkout Digital Downloads for members from a CDN Forum Voting on different items While that seems rather simple having to deal with the three different payment gateways is a big pain in the ass. Django has a great payment library which works for all three but I'm not able to find one for any of the PHP frameworks. Anyone have any suggestions? I'm posting here as suggested by someone at Stackoverflow.
