Have any of you setup e-commerce sites that accept credit cards as payment? I'm looking at Paypal - and for small transactions it is extremely expensive - 12-13% ($0.30 + 2-3%) of a $3 transaction goes to paypal. Amazon web payments is cheaper, at $0.05 + 5%, but it pulls you to Amazon's site, which we do not want. It looks like the other providers are sort of a PITA. Anyone got suggestions?
