Option #1: There is a box titled “Notes about my order” available on each product page. List any added specifications there. This is the best place to make notes that are directly linked to your order.
Option #2: After completion of your order you can also send a message, using the “contact” form, providing further information. Examples are: “I want the Bolt 55 I just ordered to be solid white like the GT” or “I would like this board by my son’s birthday so please contact me if I need to purchase a faster shipping option.”
