A system or method is provided to allow customers or users to bid for positions in a line. In particular, the system may determine the positions of various users in line and may set up a line bidding interface for the line. The line bidding interface may present users with various information of the line and various bidding options. The system may allow a user to post the user's line position for others to bid on. Further, the system may allow a user to post a monetary offer for another user to leave or switch line position. The system also may allow one or more users to bid for another user to leave the front of the line. For example, one or more users may crowd source a monetary offer for a user who is in the front of the line to leave.
