Well, there used to be one - and for a sweet time last year, due to a Disney oversight one could combine both that and the pre-order one (ergo, "double dip) to purchase the CD Photopass package for a whopping $49 (which we did after our trip in 5/10). Disney eventually wised up and closed that loophole, but not before scores of people on this forum (and elsewhere) had taken advantage of it.
