I just spoke to gridseed today and they are willing to sell in bulk at a minimum of 500 units @ $158 USD per unit.
I know i dont have the trust or feedback to get this group buy started.. but would anyone be willing to jump on board to manage this that's trustworthy? this is a really good price per unit and I am sure buyers would be willing to pay for shipping.
That's like the price they have been charging from the start for bulk orders. You will get 'bare' miners though. No USB cables, no power cables, no individual packaging (they are per 10 in a box I think).
