idk...i never see 1/2 hour for 100 bucks and bbfs on top of that advertised. And if the prices weren't "driven down", then i don't think there would be less scammers and being ripped off. In fact, there would be a higher motivation to be a scammer as the potential return per scam is higher. However, having said that, its true that anyone that charge whatever the market will bear. And some people can charge much more and still be very in demand depending on the individual.
