Since getting a machine for my birthday I have been searching to get the best prices and availability on the syrups. Argos at £3.99 was cheapest I could find but they are now even out of Cola. Yesterday I stumbled upon Asda Direct doing most of them at £2.00. Ordered a load and did click and collect and they are in store ready for me to collect now. Amazing. My tip would be avoid the diet flavours, they're not great but main syrups are good! And if you don't have a soda stream by supermarkets own fizzy water and dilute, save a fortune. Each of these bottles makes 12L.
