Just returned from Calis and we were getting 2.70 for the first few days and by the time we left most places were offering 2.89. I would think that it is much better to pay in ytl than sterling now. Prices have not really gone up that much from last year and we certainly saw the difference in the smaller numbers of tourists, which at the moment means that there is more competition from local restaurants, who are all trying to get you inside to eat! Along the "front" at Calis, Efes ranged from 2.5 - 3 lira for a large bottle.
Quite a few of the restaurants were offering 10% or "set menu" prices, just to get your custom.
We were in a jewellers yesterday in Fethiye, that we have used quite a lot over recent years and bought some pieces of jewellery. We got an exchange rate of 2.89, then half an hour later returned there to buy something else that had taken our eye and the rate had gone up to 2.94 !!!!
I don't think it will be long before it reaches 3 lira at this rate.
Happy shopping everyone
