I checked on the Disney site when I got home to confirm. They are not selling them at par as a promo, It is just at par if you actually compare the prices to the Disney site. They typically only change ticket prices every 6 months, but if there is a drastic change they may change before that. Remember though that you can buy them and hang onto them until you need them, they will expire 14 days after 1st use only.
Here is the breakdown on the new brochure at the
Disney Store:
...............................5 day................................7 day
........................ Child.......Adult.................Child.......... Adult
Base..................179...........215..................182............219
Base & PH...........224...........260................. 227............264
Base & Water......229...........265..................232 ...........269
Base & Both........274...........310..................277............314
You can add no expiry when you get to Disney if you wish.
I hope this helps out.
