Can I use PayPal to pay in stores?

• You can use PayPal to shop in stores, with various payment methods.
  
  Set your payment preferences:
  When you use PayPal in stores, you choose how you pay. When you activate in-store checkout, you'll be prompted to choose your preferred payment method, then your backup payment method. You can use any combination of available payment methods, such as your PayPal balance, bank account, credit card or debit card.
  
  To change your payment preferences:
  
  Go to your Settings.
  In "Payment preferences", scroll to your payment methods, then click Update.Your in-store purchases then will settle instantly using your preferred payment method. If there's not enough money using that method, we'll use your backup payment method instead.
  
  Changing your payment preference in the store.
  You can use a smartphone to update your payment preferences in the store, but it's best to do it ahead of time. Updating your preferences before you go to the store will help checkout go more quickly.
