I bought my late production gen1 M&P9 in early July based on the rebate program that was going on at the time making the handgun affordable enough I could justify buying it despite owning others (if I sold one of my other cheaper handguns which I did) That was in July and I immediately followed the rebate steps on their website to a "t" including the upload of all relevant receipts. I contacted S&W CS and the rebate people on 7 separate occasions. Was always told, dont worry just wait a little longer. Now, 4 months later (!!!) I get a letter that tells me my "reciept was missing or invalid" and I have to reply within X number of days ( most of which have already passed) or I will forfeit the rebate. This is not the first time that a rebater claims the receipt was not included or invalid. Seems to happen with many retailers almost w/o fail when the rebate is higher dollar (but I originally felt safe with S&W.) This is why I believe this is an intentional stall tactic, as its common "happenstance" one suspects they know many will not respond to such letters or "too late".
