B&H did not honor their own prices

I am so mad with B&H photo video, one of many camera retailers based in NYC. Pretty much, they care about money than about their customers. I bought Two canon Rebel XTi at a good price from them and they told me it was a price mistake. They stated to either buy at their wanted prices or cancel it. They don't want to honor their own mistakes and I believe it's not a price mistake, it's not even 1/2 price. I might only be a small potato for their businesses, but I contributed too. I will pursue this matter to the court if there is no resolution from them. I am so mad, mad, and mad and my vision about them has changed 360 degrees.
