Are TV prices going up or down?

Yes it will. The price of the older models of Televisions always goes down It is only the newest most advanced models that might hold a price at the level of current models. Mot only do the models become cheaper to produce over time, but they have recovered some of the fixed and R & D costs and are able to lower the prices and still make a good profit. The lowered prices increases sales further lowering the cost to produce so that is why some of the even older models can be sold so cheap
