Well it does cover some functionality of what i'm looking for combined with ubercart product powertools but there are still major differences to what i need:
- with marketplace the marketplace seller will receive a commission and the sell price goes to the website owner but i want the money to go to the individual marketplace seller and the website owner to receive a comission.
- as each store will have lots of products with very little data (title, description, prize, no dimensions, weight, etc., fixed commission) i would really prefer to create tables in order to bulk create products instead of having to click create content each time and assigning that content to a store and catalog.
