I too, am from montreal. I checked out the prices on Henrys then checked B&H....
SubTotal $3499.00 (US? already clicked canada doesn't specify)
Customs CLearence $184.41
total $3,708.46 (+tax...~200) = $3,908.46
Subtotal $3,799.99 (CAD)
Then, I went to my local camera store (Camtech Photo)... from whom I've bought a couple of lenses from at the best prices...
Told me $3900.... then told me that that wasn't the final price but they would know on monday and would call me then...they expected it to be much less then that (~3600 I'm thinking???) ... and they went and checked all of the sites for me...and said that they would definitely be lower then that...
So, I've supported my local business and left a $100.00 deposit with them to put me as #3 to have pre-ordered a 5DmkIII from them. (they did say that if i decided not to want the camera they would give me my deposit back and no big deal)
Hopefully they will be just as quick as the online dealers, and I will have supported a local, canadian business..
