I saw Beach Camera running the same promo. In fact, the web page design looks nearly the same. So the two business entities are probably related. Beach is legit outfit, I bought my Samyang 35/1.4 from them. No the same level of customer service as Adorama or B&H, but not some fly-by-nighter.
I'm sure these are stripped from 5D2 kits. No harm, no foul, and a great price.
