Good luck getting no less than $525. If you ordered them months ago you should have paid under $400 for them. Dont be greedy.
The price is the price. I paid $490 each for them (plus shipping), I would not say $525 is greedy. If no one buys them I'll just end up mining with them. No big deal either way
I paid $309, with free shipping for 15 of them. You sir, made a bad purchasing decision.
Advice: Sitting there not mining, they are loosing value everyday, as we approach the next upgrade cycle. The GPU market is reaching saturation, particularly with GridSeeds popping up like weeds. $425 is steep for those, but I think you'll get them sold for that. Accept your loss, or pay $400 for another AC unit.
One more thing, Summer is coming. How many other people do you think over bought on their GPUs and will have no way to cool them? I'm anxious to find out.
