2. Input a zipcode to calculate shipping and keep Delivery selected
3. Proceed to checkout and when asked to input an email use one from a registered user
4. Checkout will show a pop-up message informing your personal data was retrieved from past purchases
5. Change from Delivery to Pick-Up and try to complete the order (the error message will show)
