Same here Yair, Leaf US people that I talked to have no idea about the ad, nor do they know if the sales are handled directly by Leaf or through dealers.
I'm not in the US and I don't work for Leaf America but I know quite a few people in the MAC group and they are highly professional and very knowledgeable in dealing with their main products such as Leaf, Mamiya, Profoto, PocketWizard X-Rite, Tenba and Eizo.
I should also add that MAC is a distribution company and therefore their products are only sold through dealers. I'm 100% sure that every single employee there knows that very well.
At least for Leaf and Mamiya I can say from 1st hand experience that there are very few distributors world wide that provide such a high level of support and dedication and this is true not just in the photographic industry.
