HTC is a great place, don't get me wrong. I got my tragus pierced here and it's doing fine, but my experience here wasn't as positive as my experiences in other shops that do piercings.
The jewelry is really expensive, because the charge is $20 per stone. And then the extra charge for the stud kind of sucks, especially when they want you to come in and get a shorter stud after the swelling goes down.
I know that quality piercing is expensive, but I've gotten quality piercings done at shops that are not specialty piercing (HTC) and have had a much better experience overall.
