Shopping Cart/Store Front software

[brockj]

We are in the process of setting up a small online shop where employees can purchase gear (shirts, jackets, hats, ect), and I am looking for a free or inexpensive storefront/shopping cart application for this. I have never worked with anything of the sort before so I thought I would ask here first. It will be running on a windows server and we have MS SQL for a DB. No real requirements for the software, everything will be intranet only, though if it is possible to either create coupon/GC codes or allow credits on an account, that would be awesome. Any suggestions?
