I know there's a Waitrose deal on here but you have to buy 2 to get them for roughly £1 each. With this deal you can just buy the one if you don't need two, and save your money!
I don't even know where any Waitrose's are either, none within travelling distance anyway!
Only had a quick scan but flavours to choose from were....
There's also the usual Quidco and the possible use of the attached vouchers, which includes double Reward Card points. Could be a nice healthy filler for you and give you points towards your next Pizza Hut visit!
