Simple e-commerce solutions. I have a fully built site, with individual webpages pointing to specific product items. I simply want to add a backend shopping cart functionality that resides on the server, without relying on PayPal. Whats the best opensource solution that allows me to pass a variable (ie, add a "Buy This" button to already-designed pages) to a shopping cart php function (inventory isn't necessary at this point) and allowing checkout/payment?

Increasingly many e-commerce sites and ebay vendors seem to be using paypal as the outfit that also handles their ordinary credit-card (i.e. non-paypal-account) purchases. This doesn't work, and blows the transaction. How can I evade this yet-another-paypal-gotcha? [more inside]
