An ecommerce platform, available via an interactive electronic resource, allows a user to purchase products and services from the resource, receive promotional-valued credits in return for the purchase, and play games to earn additional promotional-valued credits. The user can purchase products and services at the electronic resource with either or both of a government-issued legal tender, such as the U.S. dollar, or a virtual currency used by the electronic resource, such as the promotional-valued credits. In embodiments of the invention, the user is guaranteed that an amount of legal tender (e.g., the U.S. dollar) paid-in to the ecommerce platform is the same as or less than a fair market value of the products or services purchased via the ecommerce platform. |
