Will I be able to use the Ecommerce extension that is call Storefront by Znode? Is this compatible with Windows based hosting? If not, how do I tell which extensions are ok for use with Windows based hosting (in regards to Ecommerce, I need a shopping cart and such).

i am not sure on this third party famework,

but you can use WCF to implement Shopping Cart nicely & simply with advanced futures

Thank you for your reply. Where can I find out what all this will allow for? Will I be able to add custom options, offer discounts with coupon codes and similar? I need to find one that allows custom tracking if at all possible and aslo to have dedicated support. I hope this cart will work, this is getting to be a bit of work here :D.
