Are the summer holidays eating up your wallet? If so, Italian consumer body Codacons has 10 tips for making the most of your money. Codacons says you can save up to 30 per cent on your holiday by following these simple instructions: book online if possible, or shop around at travel agents; reserve plane tickets well in advance, but also look out for last-minute bargains if you forget to; cut down on motorway purchases (which can cost up to 50 per cent more than in the supermarket), and remember ways to save petrol (not overloading the car, inflating tyres to optimum levels, turning off the air conditioning, driving at a steady speed); take a train instead of a plane for short hops, and when you arrive try go to free beaches; choose bed & breakfast rather than full board, and check restaurant prices before you ask for the bill.
