Barclays are still charging £30 for you going over your overdraft i notice...
Actually, i went over mine not long ago by a few quid, they added a £30 charge, then a direct debit went out the next day and i hadn't been online to check my account- anyway Barclays had transferred the amount i was over from another of my accounts, leaving me only the £30 charge over my overdraft. Never known them to do that before!
And they sent me a letter to say it was to "help me avoid further charges".
Nice of them

Or they could just NOT charge £30 once a day for a max of 3 days per month for me going £5 over my overdraft, meh.
