Rebates take a certain amount of time and effort from the consumer – figuring out the rules, filling out the forms, preparing and dropping off the mailing, cashing in the check, all whilst keeping track of the paperwork in the process. Thus, a rebate can be thought of as being paid to do this paperwork and provide one's personal data to the company. Chances of rebate mailing being lost or failing some criteria may further reduce the expected return on this effort.
