Update: Sorry for the misinformation. Tattoo 13 is still doing the Friday the 13th promotion, but the deal is now 13 choices for a minimum of $60, which are much larger than the $13 choices were. Still a good deal for quality work!
Apparently, it's a thing for tattoo parlors to offer $13 tattoos every Friday the 13th, and Oakland's Tattoo 13 is the place in the Bay Area to get yours. The deal consists of thirteen image choices, such as an anchor, skull, ace of spades, flaming heart, cross, and some other more creative choices thrown in each time.
Naturally, customers can expect a line out the door and a huge waiting list, but there's reportedly beer and BBQ while you wait.
So head over and feel the burn!
