Hi, although I like the idea of the cart it seems to lack the ability to force customer registration and login which is a general requirement prior to going to payment processor on all my clients stores. It seems that it is designed for very small stores that do not operate their own back office system but rely on PayPal to store all Customer/Order transactions. Can it be integrated with a Customer Login or have I missed something?

Hello Bob,
The Sliding PayPal Shopping Cart does not have a built in user login system. It works as shown in the showcases - when the users click the checkout button they are redirected to PayPal, where they can pay.
