Only thing that interests me slightly is the headband and the ears, which I don't need and probably won't be there Friday afternoon!
What is interesting is the pin/magnets shown. I asked RD specifically if the preorders would be available at the expo and was told "Please know, these items are only available during the registration process and will not be available during the runDisney Health & Fitness Expo." I am going to be fairly annoyed if it is all the same stuff, widely available and I got duped out of my discount. If they had just said, preorder guarantees you the merchandise, I still may have bought and looked at it like insurance. But, I was told it would not be available without preorder.
