Cadbury Fingers are currently on offer in Morrisons - buy 2 packs, get 2 free. There's a new dark chocolate and mint flavour, dark chocolate and orange flavour, and double chocolate (ie. chocolate biscuit with milk chocolate). They also have the white chocolate ones.
I got the white choc and the dark mint ones - the dark mint taste quite nice, but not quite 'minty' enough for me. The white choc are lovely.
