Went to Target earlier this afternoon(Tuesday). Couldn't find it out on the shelves. Told me "it's on its way". Went to pick up at Barnes and Noble, I ordered one. Turns out same price $42 plus tax. Only difference, no extras in the B&N book. Not to sound dumb, but...three is a sticker on the shrink-wrap of the book - Scan this code for bonus features. First, how to do. And Second, what will this show me?
