Methods and systems for facilitating subscription rights sales, typically in the form of season ticket sales, between buyers and sellers. Ticket holders are provided with the ability to identify selected tickets and to flexibly and easily establish criteria under which they will entertain offers to sell these tickets. Ticket holders may thus monetize unused tickets, under favorable conditions, based upon individual offers and without the requirement of a definite commitment to sell. Concomitantly, buyers are provided access to a large base of potentially available tickets, which might not otherwise be available for sale. Buyers may assemble offers based upon seller criteria and, in some instances, useful historical information. The invention facilitates the buyer/seller interaction by publishing available ticket information in useful formats, collecting and providing buyer offers which meet seller criteria to sellers for consideration, facilitating communications and negotiations between buyers and sellers, and facilitating the actual purchase and sale of tickets.
