Sorry, guess I thought it was more self-apparent than it was. During E3 Futureshop thought it would still be a full-priced ($64.99) game, so the "deal" was to get it for $46. Now that it's releasing at $44.99, I called them up to correct it. The lady on the phone seemed kind of new, but after I explained the situation she put me on hold, presumably checked with a colleague, then just applied a $20 discount to the game. It should have been a couple dollars less than that but at that point I didn't want to confuse her.
In short: if anyone has Captain Toad preordered on BB or FS, check to make sure you aren't paying more than MSRP for it.
