i think demand and supply might be the factor, less demand and more supply means cheap, but not always it also mean sometimes crappy work.
I have noticed that in almost every section prices are down. It would be nice if DP had some way of tracking this so that we could see market trends. Right now is a good time for people just getting into the industry to purchase services. btw for you tards... it is "supply and demand" not "demand and supply". That just sounds weird.
