Canon Price Watch. https://www.cpricewatch.com/contact/
I have bought bodies and lenses via CPW in multiple transactions and I have never had an issue with any transaction, though the actual retailer changes.
Never buy any new Canon gear (and a few other manufacturers) without emailing Gordon over there, he will find you the best possible deal from either USA Canon dealers, Canon Canada dealers, or grey market dealers if that is what you want, it is your choice. You know where the deal is coming from and you are sending the money to a respectable brick and mortar store, they just can't advertise the price because Canon won't let them.
I was nervous initially but as Scott says Gordon is competent and you're purchasing from a well know dealer. In my case I also discussed other items with the dealer and all activities were straight forward and efficient. Both the 1DX2 and 400 DO came from CPW with sizable savings. Not great for the local store. The R I also bought from CPW but I had given the local store the opportunity to match, which they wouldn't (were not too far off but the adapters made the difference).
