We are going to Cavtat mid August self catering. Can anybody supply any info on prices for basic groceries.

Milk, Bread, bottled water, butter, jam, eggs, salad items, meats (chicken, lamb, pork), fish, beer and wine.

Obviously we will eat out some of the time but I enjoy cooking so some time will be spent on the BBQ or Stove (in the Keith Floyd style of cooking "hic!").

Any info appreciated.
