That's the only place that you should be buying from. Check the bitmain store and buy from there.
they can only ship at the end of January
So what ? I prefer waiting 2 months to get my gear delivered than buying from somewhere else that promises some useless stuff.
Believe me you're not the first one who tried to buy from somewhere else just because they couldn't sit tight till the stuff came.
And guess what happened ? They got totally ripped off and the site turned out to be a scam and he lost about $10k poof just like that.
Don't buy from anywhere else. The main site is the only legit one. You've been warned. Don't come later on explaining how you got scammed.
I'll try to look for the thread that I'm talking about.
