Answer:
Depends on the shop. Usually, if you go back to where they were done, they'll do it for free. If they're decent, they care more about your health and the possibility of scarring more than getting compensation for it. They might charge a few bucks because they'll have to re-sterilize the tools and whatnot. * I'm assuming that you meant dermal anchors* If its a bar, I highly doubt that they'll charge anything at all since its a fairly simple removal. Call the shop and ask them about their policy
