it costs basically nothing to change banks. you sign up to a new one and they transfer your account and direct debits. you just tell your employer where to send your next salary payment.
Sorry, not available where I live and not the bank I can use for what I need. I won't give personal details but my options were limited for multiple reasons.
Small comfort for whoever needs to use that bank. This is the disconnect geeks and Free Software needs to bridge to make any headway.
