Prices are like that for a reason.... generally those lower cost countries... China, India, Tyrkey etc... lots of clicks, generally lots of fraud and very low conversion. The prices are based on the general quality of the traffic, it makes sense. You'll find most PPC companies implement similar pricing models and/or publisher payments for clicks from those countries.
