Hello,
Can anyone recommend a script for running a PHP based PayPal shopping cart/store?
I'd like to be able to customize items, products, categories, etc...

Looked briefly at phpcart which seems good,
any thoughts?

Hopefully some free ones?

Thanks

Oscommerce... the best

Xcart is by far the best. It uses the Smarty template engine and is very easy to modify.

www.xcart.com

If you want the features of oscommerce in an easy to use package, go with zencart.com
