Take your pick of supermarkets in Calis, so many now from Kipa (which belongs to Tesco) to Migros and Tansas ask for a card in either shop they belong to the same company and card can be used in both. Cards are 1lira and give you money off the club discounts of that week, hand the card in when you go to the checkout. Also Genpa and Bim Supermarkets, Bim is cheap and like Lidl's no alcohol though. Also you cannot buy alcohol between 10pm and 6am in the shops..
There is a Pork Shop in Calis and one in Fethiye they sell Danish Bacon and it's extremley good we always buy it, no need to take a chance and bring it in your suitcase.
http://www.porkshopfethiye.com/They also sell lots of British things such as baked beans, sauces, cornflakes etc., There are butchery departments in all the supermarkets and chicken shop in Calis. Also the market on Sunday is good for fruit, veg, yoghurt, cheese, chicken (we usually buy chicken at the market) eggs, get there early for the double yoker eggs.
We like to go into Fethiye to the big Migros or the big Kipa for a better selection, but if you don't have transport, the Supermarkets in Calis will have everything you need.
