The price is calculated by the number of letters X the letter height. The number placed in the lettering height box triggers the price calculation. Once you've decided on the font you want, always re-enter either the letter height or the quote width so it will calculate the correct price for you.
As long as you re-enter the letter height or quote width after choosing your desired font, the price should calculate correctly. We reserve the right to refund or request additional funds for any order where the pricing isn't correct, whether accidental or intentional.
