Whenever you move into a new home, whether that's a house or apartment, changing addresses on all your online accounts is one of the most monotonous tasks that needs to be done. It's even more tedious when you have to update both shipping and billing addresses. But it's necessary, and if you regularly use PayPal, it'll be one of the first places you'll want to update.
There are many ways to send and receive money on PayPal. You can use an email address, a phone number, or a PayPal.Me link, but if you're standing right next to the person you're trying to pay or get digital cash from, the easiest way, by far, is to use QR codes.
How To: Change Online, In-Store, Google Pay, Samsung Pay & PayPal Cash Card Payment Preferences for PayPal
Making a purchase through PayPal is great because you have the option to pay using your account balance, a bank account, debit card, credit card, rewards balance, or even PayPal's own credit product. You need to pick one to be your preferred payment method for each in-stores and online but, unfortunately, changing these preferences can get a bit tricky on your iPhone or Android phone.
