You may want to go through their website and see if there is some sort of disclaimer stating that they have the right to refuse a purchase in the event the site lists an incorrect price (the big retailers usually do). If not, then wait and see if your skates are delivered. If they aren't then raise a little hell and see what happens.
Yes the store will figure this out before shipping it to you. They are not going to give you a free pair of top line skates.
I'm not sure, but send me the link and I'll take a look.
