Hi, can anyone help me with the impulse saver function with Nationwide please? There's the option of transferring spare change from debit card transactions into a savings account. I've done this once and want to do it again but can't see the option to do so but I've used my card to do a few card transactions today. Is there a limit to how often you can do it? Is it a weekly thing? Daily? Some other kind of limit? I can't find any info on the website to find out and can't get into a branch for a while. Thanks.
