Actually some of the ones I got were for requesting brochures on different cars. Sometimes you get the offers with the brochures, sometimes you don't. Unfortunately all the ones I knew about are now over. I got one from Buick because I entered a sweepstakes, but that one was for a golf duffle bag and not cash, so I didn't do it. The Mazda one I got I think I also got because I had entered a sweepstakes somewhere. The Buick and Mazda ones came in email. The others through the mail.
