liquid flavoured coffee creamer

Hi everyone!
Though I've lived in the UK for nearly 5 years now, there is still the occassional item I crave.  Does anyone have a recipe or supplier for flavoured liquid coffee creamers?  I've tried a bit of cinnamon and vanilla in my instant coffee, and the condensed milk/caramel stuff but it's just not the same. 
I have googled recipes of course, but knowing something has been tried and tested would be great 

Whittards carry flavored syrups and you can add your own cream. You could also try using flavored coffee? I missed proper brewed coffee when I first moved since instant was the norm at the office. DH and I spent lots of time searching for flavored coffees which was fun.
