better to buy Euros from UK or CDG

A question about : better to buy Euros from UK or CDG

I leave for Paris next week flying into CDG.

I will have my Nationwide debit cad with me (flex plus).

Is it better to order Euros for collection at airport or take from Airport cash machine Euros or withdraw from ATM in Paris?

any help welcome
thanks

Best answers:

• Don't take from the cash machine, fees are really high. Best thing is check on this website where is the best place to buy euros and take them with you.
  The NW debit card also charges for purchases in another currency, but you could get a credit card which does not charge anything. I have one just to travel to Europe. No fees and very good exchange rate.
