Finally decided I was going to pull the trigger over the weekend on a 5DIII, only to find out it's basically sold out everywhere online. I read on this forum that my best bet was going to a local brick and mortar shop. Walked into my local camera shop and picked one up on Monday instead -- no waiting! It was great! I think I've become so used to buying things online and having to wait a few days. I've forgotten what old fashioned shopping was like haha.
They didn't have any body-only configurations but after some prodding they were willing to give me just the body at the $3500 price. Loving it so far! No flaws that were mentioned on this thread in my copy. Both my 24-105mm and 70-200mm f/2.8 IS II are tack sharp. The ISO and AF performance are amazing--probably my two favorite improvements over my 60D.
I did have to pay tax, but as a previous poster said, tax laws require you to pay taxes on online merchandise, even if the seller doesn't charge you up front. I'm a business major and I've been studying the consequences of not paying taxes, so I'm fine with "paying" taxes at a brick and mortar shop.
