Matt,
Thank you for the response. Just to be clear, I've created a submission order with 5 comics for a private in-house signing. In order to add one more comic, then I should simply ignore that submission order and create an entirely new submission order with the (now) total of 6 comics. Checking my credit card online statement I only see a $20 charge on the date that I made the initial submission order (which corresponds to the "return" shipping method/cost), will that be returned or is there some way for me to 'cancel' the original submission order - I ask because I can find my submitted books in my online account once you have received them ... but I can't seem to find my submission order before you get the physical books. Don't know if I'm just missing where they are located in my online account or if there's no website functionality for me to view/cancel on my end - or if this is all sorta 'automatically' taken care of. Again, terribly thankful for your time and assistance with this.
*** EDIT NOTE - nevermind. What I thought may be a charge pertaining to the submission order was my order of the shipping kit. So now I fully understand that nothing was charged to my card and I just make a new submission order. Thank you so much for helping me understand the process better. I have no further questions regarding this topic.
