Since the new Virtuemart 2.x i must say that now virtuemart IS NOT a valid e.commerce cart. The team has just done a restyling, MCV, but there's a great lack of features! 1st, you can't sell downloadable goods! (don't loose time) and you should buy a plugin for 35EUR!!! 2nd, the so announced Multi-vendor feature is not already working and is not stable. 3rd, the backend is totally incomprensible and is not simple to manage 4) the software is full of bugs, things disappear, fields disapper.. this why the migrator does not works good.
I shall move to another solution. I don't want to spend money for features present in version 1.1.x! does not worth the money!! I'm one of the donators, i donated money for that project and now, the most important feature for me, downloadable files for sale, is commercial and has high cost!
