An improved system, device and method for accessing features of digital products with assistance from a product distribution site are disclosed. In one embodiment, a user of a client device may have previously acquired rights or permissions to access one or more supplemental features of one or more digital products (e.g., application programs). Typically, a user would purchase an application program and then sometime later also purchase supplemental features for use with the application program. In one implementation the supplemental features can be purchased using the application program with the assistance of a remotely located product distribution server. Sometime thereafter, in some cases, the user desires to make use of such previously acquired one or more supplemental features on another client device. For example, the user may wish or need to transfer from a former client device to a new client device. As another example, the user may wish to utilized (e.g., share) such previously acquired one or more supplemental features with another client device associated with the user, such as another client device within user's account.
