SellFee is the first eCommerce builder-game in the world where users build real eCommerce dropshipping stores and learn to manage and market them as they play challenging missions and quests. The store & stock creation is done completely automatically through the game by the users while they go through the initial setup process and managed by using the in-game store management tools. As players progress in the game, they upgrade their stores, add new products to their stock, and earn actual money by generating sales in their store - hence managing a real business from the palm of their hand by playing the SellFee game.
