I don't know the age limit for either of these places, but I've had mine pierced at Wal-Mart (Memorial and Admiral) and at Claire's (Woodland Hills Mall). Claire's is probably safer and with a smaller number of associates, they're probably better trained than someone you'll find at Wal-Mart. Claire's also gives you a big bottle of ear care antiseptic, so you don't have to worry about buying that too. I've never had a problem with any of my piercings (two in the ear lobes and three in the cartilage), so I'm sure you'd be fine if you went to either of those places. Good luck!
