IMHO you could very easily raise the price to $15 and probably not lose any sales. Having a low price still has to overcome the concern of trusting your credit card to some website. Once someone has overcome that hurdle, 8 vs 15 is a tiny difference. I had software I sold at $25 originally and eventually had it at $99. Also, price signals quality.
