We can purchase slimline tonic in our local shop in ciftlik ,so you must be able to get it in other places,but i think that its there local brand of tonic,although the normal tonic is scheeweps.Also they now stock a large amount of british brand food stuffs including sharwoods curry sauces etc.
We just drove over to Ciftlk and tried all the Markets. None of them sell slimline tonic. We asked them all and each one just showed us the normal tonic, when we said light, they said they did not sell it. I am gutted, I was so looking forward to gettting some. Phil, was not best pleased at me getting him to drive other there..
