Talked to a couple sources now. Official Pix, who will be selling the photos and autograph coupons, will be accepting Cash, Visa, and MasterCard. According to Mary Franklin - Lucasfilm: The CIII Store will accept Visa, Mastercard, AmEx, and Discover. (Cash too, I imagine). She could not comment on the independent dealers, but stated ATMs are located in the center. I would expect most would take cash, and your more organized dealers will take credit. A few smart ones, like Ultarama, will probably have a laptop ready for Paypal use. Anyone have any more they can add?
