I see this site is low quality site dude but I have not used this site buy the hardware. I still goes with the resellers in my country and for the GPU in the local electronic market as well.
Nope, if you want to buy the hardware like ASIC and PSU and all you have to go with the bitmain site to buy it. There are many scam site revolving around the internet so be careful and research more about this site dude.
