Hi Bode.
Bread costs between 1 & 2 tl a loaf depending on whether you want sliced or unsliced, white or brown. Sliced brown is at the dearer end.
A 2 litre bottle of milk cost approx. 2 tl. As for butter, by proper I guess you mean salted. We only know of 1 place that sells it in
Icmeler and that is Costa supermarket on the main crossroads. Its expensive at approx. 15tl because its imported. Unsalted butter is approx. 4tl.
Prices will probably have risen slightly by next year, as they do in the UK, but local produce like fruit & veg, chicken & eggs are cheap.
Hope this helps.
