Abstract: A method of providing real-time market prices to purchase access to the desired places, products, events, services, etc. includes the step of providing a user interface through which a real-time, market-based, variable price for accessing a preferred position in an existing queue for a scarce resource is presented to a user, whereby the user may purchase access to the preferred position in the queue at the real-time, market-based variable price. The user interface may be provided through a mobile electronic device. In one example, a system for providing real-time, market-based access to a scarce resource includes: a mobile electronic device; and a user interface enabling a user to purchase access to a preferred position in an existing queue for a scarce resource at a real-time, market-based, variable price through the mobile electronic device.
