Of course! Simply go in and raise your pledge amount by the total amount you want to add, and send us a note of what you added so we know. For example: You already pledged $55 for a shirt and both colored sets with a sticker, but you want to add another set of flesh colored figures. No problem! Just bump your pledge up by $12 to cover the flesh set, keep your incentive marked at the $55 spot, and send us a message of what you are adding for the extra money. We will mark a note on the back end so we know what it's for. Thanks so much for all the help!
