Well, since someone is asking about your worst experiences with Mail-In Rebates(MIR) then I am curious to know what rebate offers have been the best for you.
Personally, my best experience with MIRs was with Logitech. I bought a cordless joystick, Z-560 speakers, MX700 mouse, and two dual optical mice and two elite keyboards from them all at different times with different rebate offers. Every time I received the rebate check no later than 6 weeks from when they received my receipt and MIR info. And, they even would email me to tell me that they had mailed the rebate and sent a tracking number too!!

Now
that's service!
What have been your best experiences?
