Single product website

I have a website with a single product. My site is ASP.NET based, and I just installed ZenCart 1.3.8 on it. I have signed up for PayPal Express Checkout.

What I want to do is add a product to the cart from an ASP.NET page, then redirect to the cart page so they can checkout. Is this possible? Is there a better way to do this?

The short answer is no. You could probably kludge something, but it's hard enough to make Zencart into a backend shopping cart script without having to cross OS's.

Zencart is really meant to be your whole site - picking out pieces of it rarely works.

If you only have one product, switching the whole thing to Zencart shouldn't be that difficult.

The experience is controlled by sessions for security/integrity reasons,
It can not be utilized piecemeal without breaking the sessions
