There's no legit shops to purchase S9 miners at this time. You can buy direct from Bitmain Tech but they are shady as f*ck. If your S9 arrives DOA, Bitmain Tech will ignore/deny/lose your warranty claim. They are shady as f*ck. As others have pointed out, their US distributor, Bitmainwarranty, is better but they're out of S9 and unlikely to receive any more from Bitmain Tech which is a shady as f*ck company. Did I mention Bitmain Tech is shady as f*ck?
Well they are not as shady as fuck.
They send the gear to you about 99 out of 100 times.
In my case I have placed more then fifty orders since dec 2013.
All of them were sent to me fairly fast. 58 of 60 worked okay or better them okay for me then a year in each case. That is pretty good.
Now here is the bad part.
If you get shitty gear which I did two of say 60 orders they are not good on warranties.
One problem unit they promised compensation to me and to many others that got them.
I asked them from October to May for promised compensation. Of 150 usd. They finally sent it to me after me then seven months of complaining on this site.
Now to call them shady as fuck is wrong,but if you have an issue they suck is true.
If the gear came slow. It the gear came broken say 25% not 5% or maybe 3% . I would agree they were shady. I would say. Whatever you pay add 5 to 10 % for the few that will break resulting in poor service.
