I've worked a bit on making Umbraco taking care of larger eCommerce sites but I'd say that I've never made it work as intended. So although this might be the wrong place to post I really consider using other systems for eCommerce as Umbraco at the moment has no well-working solutions taking care of this. Question is which one? I’d like to stay in MS world… Anyone got good experiences to share (not needed to be free, but affordable).
Haven’t had the time to test it yet, but I guess Courier could take care of some parts of the job if one decided to stay with Umbraco? Still quite a few issues to deal with such as the backend with lots of products to edit and keep track of etc., custom sections for orders and so on...
