Yeah, I almost got scammed right after Christmas, Sig Sauer closeout sale. EVERYTHING looked kosher, the prices were too good to be true, and about 4-5 clicks in, the URL changed to something really weird - not even close to anything Sig or purchasing-related, so I bailed.
Interestingly, for about 2 weeks, I got emails reminding me of the bargains, and urging me to finish the order. Those I deleted quickly.
