It is, but can't say no to an old friend who so happens to be a fellow, optimistic miner.

Hard to tell at which prices people are buying, judging by the verification process that goes on some of those groups where people report successful deals, there doesn't seem to be much of action even at these prices, also by looking at the last item listed you would have probably come to the same conclusion, some sellers are selling cheaper than Bitmain, so they bought those $1900 deals with a 30% discount which is $1,330 + the coupon value which is roughly 30% of face value so 1330+ 171 = $1501 and they want to make an easy $300 profit.
Mind you, some folks in the U.S would still get that deal knowing that the seller secured an easy $300 profit, you know why? because most of those Chinese resellers will declare the shipment at a ridiculously low price (like $200 per gear) and then trump tax becomes almost nothing, so, 1800+50$ tax + shipping vs $1501 + 475
1,976+ shipping for a direct bitmain purchase.
1,850+ shipping through those resellers.
In fact, one of the suppliers I used to deal with told me they can deliver mining gear to the U.S at almost zero tax, don't ask me how because I don't know, but I am pretty sure they have their ways, this explains why in most cases U.S small miners are better off buying from U.S resellers who deal with those Chinese to re-route the shipment and trick the law.
