Deluxe Doctor Who action figure, RRP £14.99, recently available for £7.49, now just £3.74.
I found it in Cardiff Tesco Extra, but I'm sure there will be some in other stores.
The Sarah Jane Adventures action figure set I posted a while ago was still there in plentiful supply as well. ( http://www.hotukdeals.com/item/142835/sarah-jane-adventures-action-figure
Both were in a seperate area to the main toys section, with loads of heavily reduced toys, furnishings, etc.
The figure features the Face of Boe from the episode "The End of the World", "New Earth" and "Gridlock" (and a few more if you know what I mean ;D), with wheels and an animatronic mouth.
