I happened to walk into a Ritz camera today (killing time waiting to meet someone), and the highest Canon model they had in the shop was a T3i. Nothing but lower end EF-S lenses, and flashes topped out at a 430EX II. Ritz/Wolf isn't the first (or second, or third, etc.) place I'd think of for a high-end body like a 5DIII. I suspect they don't get much of an allotment from Canon, but I also suspect their order list is rather short...
