I got a letter regarding my rebate today...
MPC Inc said they were denying my rebate due to "Invalid Receipt", when I had included my receipt from PSA that had all the required information. (heck, it even had my Visa last 4# !)

Good job Smith and Wesson, you scammed me out of $75.
Enjoy it. Guess what brand I won't be buying in the future?
