Well, when I was at the Post Office buying my Travellers' Cheques in June, the girl asked did I want Euro or Sterling, and I didn't have a clue, but a boy behind me said to get Sterling, coz he'd bought the Euro ones a few months before, and had lost about �80 when he changed them back. There was talk of commission and exchange rates, but all I remember is that he lost �80 and I didn't want to. I bought the Sterling, and all was well.... Happy holidays!
