Abstract: An electronic product registration system which manages and validates manufacturer rebate programs to assure that such programs are carried out in accordance with appropriate rules and procedures. The invention reduces or prevents improper rebates from being issued and/or improper product returns from being accepted in connection with products sold with a manufacturer's rebate program or the like. The invention also assures that proper refund amounts are issued for returns when a rebate has been previously provided, as well as provides a tool for enabling the retailer and manufacturer to properly account for refunds and rebates between one another.
