I don't mind if I am Mrs Nationwide Karennina
I think the NBS is great, I love the fact it is still a mutual Building Society and we voted and won to retain its mutual status against those that seek profit over people, much to the annoyance of those who didn't in the hope of making a quick buck. It is the reason I was a member in the first place long before the Flex account and free overseas withdrawals in GBP was an issue in my life.
I am sure they are more than well aware of what they deduct in charges from our accounts and what they could and don't. Long may it continue.
