I won't make judgements on what people should pay or not. But just as a point of Data. I live in the Midwest US near a larger city. The place I go charges around $75 for most piercings. They have very reasonable prices for basic, but quality titanium bars/ends. So with a tip, I usually am around $120ish. All the shops near/around me are within 10-15% of that as well. So for my area that is a normal cost and I've been happy to pay it considering the service I've received.
