Well, I can't comment on that, other than saying that it is their business strategy. You can try insisting on the advertised price.
From the finance point of view, as long as the discount over a local warranty set is sufficient, I don't mind a gray set.
From my experience consulting for the manufacturing sector, it is best to avoid the initial batches, or to at least get a set with a manufacturer warranty.
So here you go. If you want it cheap, there has got to be some risk involved. That is why they offer a discount over a local set - to offset the risk. Whether the discount is sufficient is your own judgment.
