Hmmm... You know Zack, for a situation like that, I'd have contacted OMGCNFO via E-mail at their sales address if I were you to explain my situation. Then, hopefully, the guys over there would've contacted me and gotten my order through via the phone once I were to have called them. And the payment methods, if available would've been explained to me and the payment via MO made.
Course, that wasn't my situation. I was trying to get my payment through via methods alternative to paypal.com, contacted them via E-mail and Ben helped me once I called on Friday afternoon.
Got 1 single pack, but that's all I need for my collection. For now...
Maybe you can get in touch with someone going to SDCC, or place a post in the "Penguins Hookup" thread over at Palisades.
