Cheers for the advice guys, got my nationwide account opened with an OD off £750. Just waiting on my pin now, and details for online banking.
My intention was for my parents to do all my online banking here in the UK while iam away but, iam sure you cant access you balance at foreign cash points, which would be a problem. I will be able to keep a rough guess.
Iam thinking that I will transfer most off my money that is in barclays account to my nationwide account, and take both cards incase I lose one, and an addition credit card.
Those who have experience, how did you manage you money while you where away?
