Just a heads up to check the exchange rate if you are buying Euros in a Thomas Cook store. I saw the rate in one of their stores at 1.11 and later that day went into my local store to buy. I nev asked rate and none was quoted. My receipt was put in the envelope with my Euros. I never opened it until I was on holiday and was shocked to see I had been given an exchange rate of 1.06. Given that the PO is right next to the shop and had a rate of 1.11, guess where I would have bought.
The store called me today after I complained, at which point I said the Euro had never been as low as 1.06 this summer, I was rudely informed that it was 1.05 today. I hung up and called another Thomas Cook store who told me today's rate is 1.11. So seems if you don't ask they may well rip you off. Having googled the subject it seems it's common place, so take care folks and check the rate before buying. No point in getting a great deal on here and then being stung for travel cash.
