This scheme is not too different from others like buying money orders and deposit it back to the bank. I don't see why people have no problem accepting the MO scheme but not this one.

How about this? I saw a lot of Ebay auction items which came from people buying stuffs online (like officemax.com) and getting a rebate. How is the moral issue for those people??? In short, a lot of people are gaming the system. This particular scheme is definitely not the worst one I've ever seen.
