Which price? The $59.95? If so, that price has been in effect for a little while (about a year, I'd say; Is that right, Dizneydaz?). Apparently the DLR PhotoPass CD used to be higher than it is now. I don't think we have any word on when DLR will raise the CD price, but I am sure they will at some point. Right now it makes no sense to hike up the price TOO TOO high, because there are only 2 parks after all. The WDW PP CD price makes much more sense because there are PP people all over all four park as well as a hotel or two AND the water parks.
I just think a lot of people assume that they will get a better deal to pre-order a CD for their DLR trip, but really that only works effectively for WDW.
