This info MIGHT be wrong, and if anyone has been there in the last week or so and knows otherwise, they will jump in.
But the last time I checked, the actual price is the same.
If you are specifically talking about the CD, in the parks they have been keeping the price the same as online, but it is NOT possible to edit the pictures (you just get the plain pictures) and you get a few free 5x7 prints.
If you order online when you get home, you paid the same price (plus shipping), but you get to edit the pictures before ordering the CD; putting borders on, putting signatures on it when you've had an official character picture taken, cropping them, etc.
