Friday the 13th is back, and tattoo lovers will be lining up for some cheap ink. If you're headed to these Denver shops, you must be at least eighteen, with an ID; these deals are first come, first served. Bring cash. And don't forget to tip. Here are ten tattoo shops celebrating Friday the 13th:

Certified Tattoo
11 a.m. to 8 p.m.
8025 West Colfax Avenue, Lakewood
Certified Tattoo will be taking all customers who are in line by 8 p.m. This isn't the shop's first rodeo: Designs will be available to view on Friday, pre-drawn flash tattoos will cost $20, and, by the way, you can pick an unlimited number of tats. The deals are at the Lakewood location only.

Clean Slate Tattoo and Piercing
Noon to 9 p.m.
6620 South Broadway, Centennial
At this shop down south, three participating artists have each drawn a custom flash sheet, but once a design is picked, it's gone. Flash sheets are online now for perusal, so check ’em out and get there early.

Crimson Hilt Tattoo
10 a.m. to midnight
2907 East Colfax Avenue
Once again, Crimson Hilt is ready for Friday the 13th, with $20 black-and-white pieces for you to choose from and add to your leg or arm collection. No alterations will be allowed; the shop only takes cash.

Epiphany Tattoo
