I tried to order the Antiminer from the link on your blog from Alibaba, but the seller changes the price as soon as I submit the order. 

I know where NOT TO GO, Mining coin Shop is a fraud, web address is https://bitexco.us/.  They have excellent prices and they have a website so my dumb ass believe or hoped that they were legitimate.   But I was not that dumb, because as a test run I purchase a couple of Video cards with express shipping.  After going back and forth about the price, because I paid in Bitcoin, an amount was finally agreed on.  So I paid the agreed amount and after a couple of weeks I began to wonder about my shipment so I emailed them.  All they said was that the order was being processed and after two emails stating the same they stop responding.  So after 30 plus days still no response and no shipment.  SO STAY AWAY FROM THIS SITE, THE PRICES ARE TOO GOOD TO BE TRUE.
