Toys "R" Us, as revealed in a print ad in the US, is currently running an in-store pre-order promotion where you can take home a cuddly new Charizard plush toy if you purchase both Pokémon Omega Ruby and Alpha Sapphire at the same time.
The catch is, you don't get the plush until after you pick up both games from your pre-order. So there's none of that "let me try and get out of this by canceling" jazz. If you want that plushie valued at $22.99 MSRP, you're gonna have to pony up and pay for it. Or, if you really wanted it that bad you could probably just buy it separately eventually.
