I doubt that you can but high-quality targetted traffic for 70-100 USD. I know if I could find that I'd be rich. Who told you you could buy good traffic at these prices? I've never heard of good prices like that.
Not worth it! 100,000 visitors @ $60 0.25% click = 250 clicks 250 clicks x 5 cents = $12.50 Lose $47.50 for every $60 you invest..LOL! The 0.25% CTR and 5 cents per click figures are already VERY generous! Don't forget smart pricing kicking in, foreign traffic, and the traffic is delivered through a popup (may be against TOS)!!
