Not sure where you're finding these for $980 NIB. Now back in January, when I placed my order with Bitmain, the A3 was $980 then, but shipping adds hundreds more with the PSU. But using that logic, I could argue that bitcoin only cost $3k some months ago, so that's what it should sell too for eh?

I'm willing to beat the lowest price on eBay, which is  currently $1,599.98:

Will sell for $1500 each for NIB.
$1400 each for used.

Prices updated in the OP.
