Which account will be used when I make an in-app or online purchase?

When you make an online or in-app purchase the amount will automatically come out of your primary account which is also known as the account in the chequing position. You are unable to select the account you want to use, therefore, you should ensure that you have enough money in your account to cover the purchase to avoid non-sufficient fund fees or a declined transaction.
