Its become a strange tradition of sorts. Tattoo parlors for as long as I can remember, have been doing special prices for tattoos and piercings for Friday the 13th.
Some of the tattoo infections reported have caused permanent scarring. Before you let your artist start on that tattoo make sure there are no recalled inks involved.
First and foremost, none off the crappy tattoo makers (not artists) will set foot into a place that will immediately expose their suckery - so you are virtually guaranteed some high quality work.
