To all who are looking for a Wii Fit, they are available freely in the UK retail channel.
I phoned my local Toys R Us who are having deliveries every 3 days.
They called me 2 days later and put one aside for me and I collected it the same day. They had 9 more in free stock.
If you want a Wii fit, DON'T pay the prices on here. Use the phone and save yourself £30 or more plus the extortionate carriage costs.
