Recommend a Simplified Shopping Cart

I've created my own website that sells user-generated content. Since it's not a typical storefront (merchandise is constantly being added by the users), I developed it myself. Now I'm looking for a shopping cart that can take care of the payment for me. Since I'm selling content, I don't care about quantity, shipping, taxes, etc. I just want to say "pay $x on product y" (which it doesn't need to correlate with any databases) and then take care of the payment, and return that product y was paid for. Once I get that product y was paid for, I can unlock it (hence no need to worry about shipping).

Any suggestions? Thanks.

How about Google or Pay Pal buttons.

Pay Pal would be my number one recommendation. It fairly simple and should be easy to maintain.

As mentioned, I would go with PayPal or Google Checkout. Anything more would be unnecessary for your requirements.

agreed, pay pal or google
