Abstract: The invention is systems and methods for transferring items with restricted transferability. Initially, the systems and methods wait for a first consumer to make a request to transfer an item after having purchased the item from a provider. The systems and methods then send a request to transfer the item to the provider. This request may indicate inducements to the provider to authorize the transfer. If the transfer is authorized, the systems and methods then present information regarding the item to other consumers. This information may be presented as part of a bidding interface or as part of an advertising interface. Once the second consumer submits a winning bid for the item when the information is presented in a bidding interface, or an acceptable offer when the information is presented in an advertising interface, the transfer of the item can then be completed with or without the assistance of an intermediary.
