I believe ANTMINERSTORE.COM is a SCAM website.

If you look at the About page, there are a series of certificates.
I zoomed in on those certificates and found a couple of them with Best Source International, Ltd. as the company name.
I looked up Best Source International which is a company that resells in Alibaba.  I did some other research and found that a lot of scammers are using parts of Best Source's website because Best Source is viewed as a trusted company.  Best Source took a hit because of all of the scammers and they have taken action to remove as many as they can.  This one is still lingering.

Also, antminerstore.net's phone number is masked using google voice with an area code number from Arizona.
