Do some research on the tattoo you are wanting to get. Make sure you know what you are getting and if it is something you want for the rest of your life.
Don't ask for a deal, discount, break, or if the artist can cut you some slack. Cheap tattoos often are..."cheap" tattoos.
Do research the shop also. Make sure you know the precautions they are taking for your safety and theirs.
