Half litre bottles are buy one - get one free. In town centre stores this costs £1.23, but out of the town centre they seem to be £1.08. Look for special offer bottles with the 50p mobile credit on and you get two drinks for 8p. You can have 8 credits of 50p on your PAYG mobile. Choice of fanta flavouirs, including the Zero options. 32 million bottles and cans available, apparently. Bargain!
Tesco's are doing two bottles for £1.60 which is clearly pretty rubbish. Walk past to McColls!
