Abstract: A system and method to facilitate computer-based commerce is presented. The system includes a module to facilitate communicating a vendor offering to a user if the offering is within a category designated by the user as being acceptable for receipt of such offering. The provider offering includes a category code to indicate an associated category for the provider offering. If a user chooses to propagate a vendor offering to another user, the user may be entitled to a reward. The reward may be designated to the user or to a third party.
