I was in Gamestation in Swansea today and noticed that they have started a sale, there were loads of games on offer (including lots of new releases, I'm sure I saw "Alone in the Dark").
Noticed that they were selling DS Lite in black with Brain Training for £99.98, asked a sales assistant and they said that they had a few in stock and that more titles should be going into the sale tomorrow. Not sure if this is all stores or just Swansea.
Handy if you have games to trade in to save a bit more off the price!
Hope this helps someone!
