Ouch, that is a huge gap in shipment dates... Not cool at all. Not sure why they would bundle up 77 orders then wait for 3 weeks to ship the next batch.
They sent them out to all the shills and supporters of Bitmain 1st. The rest of us have to suffer, so the shills can ROI
I'm not a shill. I just happened to be ordering a B3 when the Z9 appeared in the store.
