Don't discount just because the letters are 3/4" high. If you go to a print shop, they charge a set-up fee and if you were having something screen printed, they would charge a set up fee as well. Giving a discount for volume is a different story. A small discount for more that 10/15/20 items is not unheard of but in the case of embroidery, you are re-hooping each item so you can't give away the farm. Good luck!
