I am not happy with you BitmainTech for raising the price as I am purchasing. When I added the product to my cart it was USD$341 yet when I committed to the order it changed to USD$370. How dare you rip us customers off like that. It is just not the right thing to do if you are wanting to keep your existing customers!!! How dare you change the price as an order is going through.

Edit: It might have only been 0.1BTC at the time but that is not the point. I saved up for that and don't expect a company to trick me into paying a higher price than what was advertised.
