Increase in price of TV boxes

I just signed a 2 year contract in Oct and was told boxes would be $5 each - now they are increased to $7.50 per box??? Has anyone else seen this increase on your bill? This is a 33% increase and I do not understand how a box in my house is costing XFINITY 2.50 more per month?? If I had known this was going to happen I would have seriously considered NOT resigning a 2 year contract to keep my bill at a cost I can expect monthly. VERY DISAPPOINTED!!
