UK holidaymakers are expected to spend £420 each on credit cards while on holiday this summer. Some 14.3 million people will spend £6 billion, 10% more than in 2012, according to research from Post Office Money. A quarter of these holidaymakers plan to use their cards to top-up their spending money, and 18% say they expect to run out of money and will rely on 'precautionary plastic'. According to the report, a fifth of card users don't check the cost of using plastic overseas.
