They probably don't have stock, neither do any of the other sellers, AMD chips are very very scarce lately.
Supply Ability:
1000 Piece/Pieces per Week
Yeah right :p That's why Pandaminer has been having serious issues getting units to their customers..
They're using pictures from Pandaminer, which is another seller.
They might have bought a big batch from Pandaminer and are now selling it for a lot more but i doubt it, makes more sense to just mine yourself.
So i wouldn't jump on this if i was you. But it's up to you though..
