Mendos in Taşyaka have coconut milk and the Azda's in Hisarönü and Ovacık do too - I can not remember if it is just the blocks or available in cans as well though.
Mendos also have Oyster sauce which I could not find anywhere in the Fethiye supermarkets although again I know Azda in H and O do, but I don't live there any more.
Good luck with your search
