buying euros...

[DAVEDWACK]

It appears Santander's website isn't up to speed either then.
All I can find is an introductory free fee offer for their credit card that ends in December 2016.

If you can refer me to where their debit card has no fees at all in Europe I'd be grateful. I might well sign up.

Nothing to do with their credit card at all. If you use your 123 account debit card at any atm you are able to draw 300 euros per day with no charge whatsoever and also receive that day's business rate (I may not have the correct terminology). What I do know is it's a better rate than is possible using any other method locally. I spent a month in Feb/Mar doing precisely that whilst holidaying in Tenerife.

I could show you a bank statement I suppose but really, just give your local branch a call.
