I bought one of these in Toys R Us So'ton on Monday. I have checked online but online they are now sold out. However my sister says she has seen some in her local store. Don't know if they've mostly flown off the shelves but getting this doll that is £39.99 + in most places for £29.99 has to be good.
Looks like a good toy too, it's the one with the jet pack burner.
