having been to boro twice, iv found that you normally get better rates out there, though be warned. check the rates advertised outside the exchange shops and what is actually paid.
Usually you will find that travelex give a better rate than M&S, provided you order it on the website and collect it at the airport. I fyou have any currency on your return M&S seem to be the best for buying it back. Mal
Robo- They are crap if you go to the airport office but online they are better than M&S and most others in the UK. Last year went to Canada got 2.09 from them to the £. Everywhere else it was 2.02. If I had got the currency at the airport without ordering online it would have been 1.95. Mal
