ROBUST Shopping cart software..besides Xcart...
 

What else is out there.?

But if you're looking for Robust - sounds like you're looking for custom features. Might be best to have it programmed for you.

Zen cart is great (built on OS but more up to date)

We have a cutom made content sale cart and store system with seo and content preview mods, studio reselling, affiliate tracking and coupons.

Hit me up if you are interested :)

Juicy,

Well there are tons and tons out there. I know about 98% of all carts - commercial and free. It all depends on your needs and picking a shopping system that you can grown with if needed - new mods, feature requests, etc.

If you need any help please let me know.

X-cart turned out pretty good, the shopping system was written for me and our companies in the beginning a few years ago. Programmers were good but didn't want to sell the guys fcart.com and they went there own way and changed it to x-cart. :)

Cool i ran xcart for a few years on my other site.... it was very nice but it seemed to have a shitload of security issues and what not... and the php smarty templates took me some time to get used to em.. I might just go back to Xcart seems now it should be tight
