Thomas Cook says it is "not unduly concerned" by the latest offering from Tesco Personal Finance: pay at the till' travel insurance packs providing instant cover at rock bottom prices. "Many people are happy to pay that little bit extra for the convenience of purchasing a holiday and insurance from a single location, in a single transaction," said a Thomas Cook spokesman. All shoppers need is a start date and a Tesco Clubcard. Cover for a one week trip to Europe costs just £15, less than half the price of the equivalent package in most travel agents. The service will initially be available at seven stores in Scotland and the north, with plans with plans to extend across the country towards the end of the year. {{NEWS }}
