Found 20th Jan 2016
Went to my local TK Maxx in Birmingham City Centre and they were selling Monin Sugar Free Vanilla Syrup 250ml (25cl) for £1.99. I'm not sure if other flavours are available, but this was the only flavour available in my local store. Tesco is the only supermarket that sells Monin Sugar Free Vanilla Syrup, usually for £3.00, so £1.99 is a good price for sugar free Monin syrup. And I consider Monin to be the best syrup brand on the market. So I hope this deal helps someone, especially if you prefer sugar free syrup.
