I'm ready to pull the trigger on the E-M5 II. Olympus has a promotion now so I can get the Mark II and the 12-40 for $1,898; $200 off. I have the Mark I and like the updates to the Mark II. I'm retiring in two weeks and this might be my last chance to afford a camera like this. So, my question is this: Should I be better off buying from Olympus directly or from Amazon? Thanks.
