Just been looking on internet for Wii Fit (again!) and went on HMV site to check if they had any stock. Web site said not released yet, but underneath was a message saying:
"Desperate for a Wii Fit? hmv.com may have limited stock of Wii Fit to order by telephone, so give us a call on 0845 603 8576 to check availability"
Rang them 5 minutes ago and a "lovely" woman said YES! they've got loads of stock in for £69.99 with free delivery! Made my day!!!
