Why would you buy from vendor...RRS sells primarily direct . I have bought lots of stuff from them over the years
Having said that, BH Photo is amazing to deal with as a Canadian, so if you don't want hassle of customs etc let them take care of it . If you spend $100 ( the HC-Pro is $90 ) they ship it for free to Canada and clear customs for you ! You pay duty / tax though but it's precharged and calculated once you choose the province. Doesn't get easier than that.
