Some retailers have taken a step forward with offering consumers new ways to submit their rebates easily over the Internet, completely or partially removing any mail-in requirements. Staples, Sears, TigerDirect, and Rite Aid currently offer an online submission option for all or some of the rebates they offer. These special rebates are usually identified as such and have instructions for full or partial online submissions. This is touted as a more accurate processing of the rebate, reducing the potential for human or mechanical error and, in many cases, eliminating the postage costs associated with traditional mail-in rebates, although some require the UPC or proof of purchase to be mailed in. Most of these retailers still let consumers submit rebates by mail.
