"Mail in rebates" are a huge scam that has been going on for years. They know that half the people will give up on the rebate after a couple of emails and phone calls, so that is a LOT of extra money for the company, and it is difficult to prove you were scammed unless you can afford an attorney or take part in a class action lawsuit, and when it finally gets resolved in the courts 5 years later there will be a new CEO.

Whenever you do a mail in rebate, ALWAYS send it Priority Mail, Certified, with return receipt . . . that will cost about 10 bucks. If you enclose a letter typed on paper with a law firm's letterhead (you don't even need to work there) you are a lot more likely to get your rebate with no hassle. If you just send it in an ordinary envelope with a stamp they will toss it in the trash.
