>Better to ask guys from foxtools. Personally I do not like things like "Mail-in Rebate". Why not just give a discount price?

Because this way they get an interest-free loan from the customers, and may also sell the address to marketers. And since this counts as a business relationship, they then have a loophole in the telemarketing laws - they can call you even if your phone is registered in the do-not-call database. Unless they changed that, I haven't read that page last six years.
