A very good e-commerce for DotNetNuke (DNN) is SDN Store, easy to set up and not expensive at all, you can find it at: http://www.sysdatanet.com . It has an excellent Guided Tour: http://www.sysdatanet.com/sysdatanet/dotnetnuke/GuidedTour/Default.aspx with a very popular forum: http://www.sysdatanet.com/forum where they reply almost instatntly. Most of the features are already built, however they can always add new ones for you, including installation and configuration at very competitive prices.
