(Not sure if all Asda's are doing this deal). Local Asda is selling 3 packs of Tassimo pods for £10. I got 3 of the 16 pod packs and 3 of the 8 pod Latte/Cappucino for £20, saving £4.65.
Ideal if you've got a Tassimo machine for Christmas, although the selection was limited to just coffees, everything else was sold out. :(
