Any Recommendations for PHP Shopping Cart Script Using Paypal?

Anyone have any recommendations for a PHP script that would allow me to quickly setup a shopping cart type site using the PayPal API? I already use the API to sell one-off items but I would like to enhance my script to behave more like a shopping cart so that users can select multiple items or if I can find a script out there already I might consider it rather than writing something myself. I’m looking for a script that will allow me to list an item, but once that item is sold it’s no longer available. I’m not selling multiple items of the same thing but unique items.

The last time I looked I didn’t really find anything that fit my needs which is why I went the route of doing it myself.

Opencart is a beautiful piece of wonderfulness sent straight from heaven. Try it.

I agree, opencart should be a great fit.
