Half of consumers never even try to get the rebates. Many forget about them or lose some of the required material. Other times consumers send everything off and never receive a check. About a third of consumers said they had bought a technology product with a rebate in the last six months, according to an online survey conducted in November by The NPD Group. A fifth of the consumers bought products earlier than they would have otherwise, and one in six spent more money than he or she would have if a rebate hadn’t been offered. Most who missed out on the rebates forgot to redeem them (41%). Others lost the forms, receipts or product bar codes (25%), didn’t feel the rebate was worth the effort (20%) or thought the redemption process was too complicated (14%), according to a survey by Leflein Associates Inc.
