We've recently developed a website for a client which has excellent eCommerce facilities that are fully integrated with DotNetNuke.
The eCommerce module is Cart Viper and comes with all the features expected from an easy to use DNN module. The guys at cartviper.com have been very responsive to our comments and suggestions for the product which has meant we've been able to deliver an excellent DNN eCommerce solution for our client.
