.. this is one site that believes in Customer Service. I had questions, I had answers quickly. No "wait for days", No "buy this and find out". Just courteous and HELPFUL answers. It is refreshing to find a site that really cares about their products and stands behind them! And their products perform as they promote them.John L.
When I received my ASP.NET E-Commerce application it was for the purpose of marketing my software inventory via the internet. It took a minimal amount of time to launch it and offers host of traffic tracking options for further market study and analysis. Overall an excellent product. Richard G.
