I am in Canada so maybe it's only here, get someone from Canada to confirm it for you if you don't believe me, preferably from a Vancouver Apple Store. But I did get my RMBP through it like this.Sir Al, post a screenshot of the app or I'm calling BS.
Edit: Maybe this is only for certain stores/markets...
Canada doesn't have a pickup in store option yet, so maybe that's why they just have product reservations.
