So I recently put in an order containing several preorder items, which aren't back from the manufacturer yet so the order hasn't shipped. I would like to know if it's possible to purchase another item and have it added to the existing order to be shipped so I don't have to pay for shipping again. (This item isn't a preorder, if it matters) Is it possible to do this? Thanks in advance!

Well after getting no replies in a couple of weeks (thanks guys) I just went ahead and emailed BAF from their main page, and they put my order on hold and charged my card for the new items :) Just in case this thread comes up in a search for someone with the same question.
