At lunchtime today I tried:
All out of stock, Gamestation were not doing a 'pre-order' list and had no idea when stock would be in, but did point me to their website where they have it in stock...with a Wii...for £250. Game looked promising, "pre-order now" stickers on the boxes, so I asked to pre-order and they said they were not accepting pre-orders as they had no idea when they would get another delivery.
Even though I spent literally seconds in each store I overheard numerous requests for it (and GTA4, for that matter) so clearly demand is massive.
So, any tips?! Tried everywhere online obviously and nobody is taking pre-orders. I'm sure just last week Nintendo of Europe said they were working closely with retail partners to ensure they were kept up to date with the stock situation at all times. Riiiiiight.
