I'm pretty sure that hasn't stopped the counterfeiters in other cases where there's only one provider and items are being sold directly by the manufacturer through Amazon. I think it would be fascinating if someone were to set up and provide through FBA sales of some of those products.

It hasn't stopped others, but I'm thinking Amazon, knowing it is their own product... just allows their site to sell just their stuff.

It is an interesting contrast, but wouldn't be surprising.
