That retails for 1499. No way anyone is legitimately selling it for 1500.
Well, I can think of two possibilities that could be possibly viewed as semi-legitimate.
1. Student who has not spent wisely needs to sell a gift to cover tuition / books / credit card bill / etc.
2. Relationship breakup, selling for spite.
3. Newly minted crack fiend. Not stolen from a stranger, but selling his own stuff or that of a close relative / housemate.
4. Apparently I can not count to two.
