How much when they print a shirt?

Depends on what you want on it no more then 20

First you buy a blank shift in the color you want then go back to custom design in the store and depends on the size of the letters n how many letters I think they start letters at 75 cents to 1.50 a letter depends size you can choose style of lettering n color on ur clothing as well. Depends on how many letter more words more expensive they can design it been going here for years making custom blank hats t shirts n hoodies with my own design on them lettering n color.
