Saw this console deal instore at WHSmith Marlborough today. They are basically giving away Imagine Babies and one other Imagine game (Fashion Designer?) with every DS Lite purchased.
The sign did not seem to be an 'official' head office type one, so it could be a store specific deal. Worth phoning your local store to check though.
The sign implied that the deal included all the new DS Lite colours, although they only appeared to have white and pink instore.
This deal seems to be INSTORE ONLY - and could be store specific.
