Thank for the additional feedback guys.
We realize that our ecommerce module is not mature yet, but we have a team dedicated to its development(which cannot be said for any other feature or module) so A LOT OF ECOMMERCE IMPROVEMENTS WILL BE DELIVERED QUICKLY. I know it seems that its cost/value ratio isn't the best for the moment, but please remember that we can't increase our prices every time we add more features. If we did it this way we'd have to increase the prices at least once per year and I am sure no one would like that. Furthermore, it would send the message that we are not a reliable vendor because you never know what we'll do next. Instead, we prefer to price the module what we believe it will be worth soon(i know it's less than ideal). Licenses come with a 1 year subscription and its value will be biggest for ecommerce compared to anything else in the system. That's a promise. Until then, we've given free ecommerce add-ons to all Sitefinity 4 early adopters and partners enjoy their discount on this module as well(so in that context we are talking about 20%-30% less than $1999).
Regarding Europe vs US specific features, when we cannot do everything at once we need to prioritize. Europe is our #2 market(after the US) so that's how we prioritize region-specific features. Rest assured that for us serving the needs of our European customers is and will continue to be a top priority, it just make take a little time on this one.
