It would be a difficult one as Highlander suggests - the vast area that a map would need to cover would either make the image too huge, or the detail too small to be worthwhile. If you posted where you were staying, someone could highlight where that is, and where your nearest minimarket & supermarket are.
I would also say that you can get most things that a supermarket has to offer in the small shops (mini markets) - maybe a little less choice and a little more expensive - but not always, sometimes cheaper in fact. Supermarkets in Turkey to me are a little different to those in the UK. Larger supermarkets in UK tend to offer a larger choice. In Turkey they have more of the same product piled up on the shelves...
