Wii Play including remote - £24 in store only at WH Smith
Still marked as £39.11 (ha!) on the displays but in the Holborn store in London, they had 3 boxes hanging up behind the tills in the entertainment section with £24 stickers on.
Guy seemed to think it would be nationwide as it is part of the latest 'sale' repricing and it scanned through the till no problems.
Hope this helps someone!
