Am currently thinking of using commerce.cgi, modifying it and writing a Windows-based back end. I would really much rather buy in a stable solution, though.
Anybody know of an existing product that does all of this stuff elegantly?
The more specific you want the setup/functionality of the cart the more likely you are going to have to customize an existing solution. Which obviously translates into more money.
I'd suggest you find a good off-the-shelf product and pay for someone to modify the cart to your specs. You will most likely need someone to write the offline part.
We've discussed X-Cart, osCommerce, Able-Commerce, and a variety of other products on this board. Any one of them could be modified to suit your needs. There may also be someone here who knows a product that is more closely aligned with what you're after so hang-tight and perhaps you'll get what you're looking for.
