Yes, very easily! If you’re used to making little-and-often transfers into your HyperJar account, space them out into fewer but larger amounts. For example, if you’re used to adding in £5 a week to your account to save up for something, or to give as pocket money, switch to £10 every two weeks and you won’t be charged a penny.
And instead of moving money back to a bank account, use your HyperJar card to spend – it’s accepted everywhere that takes Mastercard (that’s pretty much anywhere you can think of) - or just keep to the four free transfers limit. If you do this, there’s be no charges at all.
