Nice Price: a poor quality indicator ?

Nice price is a policy that industry uses to sell things at a lower price. Nice Price is not necessarily a poor quality indicator: you can buy good movies, good CDs and good videogames that are
not wanted as the one advertised in this time by the medias as television, radio, internet and specialized magazines.
Good things of the past aren't buy by the majority but by the ones looking for the quality things and not just for
everything is on everyone's mouth. Surely when something is sold at half price after a short period the probably its
quality is low otherwise the high quality of a thing can keep its normal price for a long time...
