You could use Round Up for this if you choose to. A Round Up account is a savings account provided with your Clubcard Pay+ account. We'll round up the amount of any transaction to the nearest pound and save the change into your Round Up account. The round up functionality will be automatically switched on for you when we open your Clubcard Pay+ account, but you can switch it on and off anytime within our Mobile Banking App.
You can withdraw money from your Round Up account to your Clubcard Pay+ account, or to another Tesco Bank account in your name, anytime using our Mobile Banking App. So you could choose to save this towards Christmas :)
