I have been in contact with HARDWAREBROSdotCOM store 3-4 weeks afo, and I have bought 5 PSU. I got PSU in 5 days after order (though they promised 2-3 business days), but maybe it was a delay of UPS service. As I understand store is in Nederland, and I am in Greece.
I did not order miners at this store because got directly at bitmain. But this is only my opinion it is not a scam.
