I'm looking for a free/open source ecommerce product. Specifically what I need is multisite support that allows each site to be branded for the vendor. Basically, I have a brick and mortar business and I'd like to provide a service that allows people to have their own website that accesses my inventory. Sort of like CafePress.com but not exactly.
I've looked at mojoPortal (doesn't have a fully functional ecommerce), nopCommerce, dashCommerce, and DNN. I didn't find a reference to multisite in the features. I suspect that DNN might be able to do this based on the size of the support.
Does anyone have any experience with the above mentioned with regard to multisite ecommerce?
