Unfortunately I am not familiar with US prices because I am from Europe. But if it is a discount and tax not included, $250 does not sound that crazy cheap, so I would not guess that it's a scam judging from the price alone. But you should still make sure you're not buying from a scammer, I cannot guarantee you anything. But if it's directly from Amazon / from a reputable seller / or if you have buyer protection, you should be fine.
