Hi, should have replied earlier, but this is the situation in Plakias:
1. The ATM's have been working all summer, yes there are times they run out of money so always make sure you have sufficient for a few days.
2. The supermarkets take cards, some of the tavernas do, the big hotels do but not sure about the smaller rent rooms, unlikely.
3. I have just found out that there is no where in Plakias exchanging Sterling so if you are bringing cash bring Euros or you will have to go to Spilli or Rethymno to change money.
4. One of the main VAT increases is on processed food which has now gone up to 23%. So basically all food apart from fresh fruit and veg, milk and bread and spaghetti are not included. I'm sure that with the increase in the tavernas (which happened a few years ago and was then reduced) will be absorbed by the businesses for this year.
