I am looking for a dropshipping solution for my VM 3 and Joomla 3 eCommerce. I have read about Webskul solution (http://forum.virtuemart.net/index.php?topic=137156.0), but I am looking for something cheaper. If it is possible, I would like the dropshiping provider to ask me just for a porcentage from my sales. If not, which one could be the cheapest option?
