Thought about it but passed for now. For me, the reason I gave it some thought is that I never (almost never), take my 5d3 to any family events like nephews birthday parties or those other "obligatory" affairs. When I show up, everyone always asks me if I brought my camera before they even say hi!
I thought it may be more convenient to throw one of the "M's" in my pocket for just such events or to keep in the car if I go somewhere just for unexpected photo ops.
I assume I'll pick one up sooner or later and I'm assuming the deal offered, although I didn't grab it, will be matched or exceeded by another deal on it again in the future... perhaps then~
