From the app... just download and select curb side pick up.
Exactly like the other poster responded. You're ordering online, when your order is ready, you get an email. There is a link in the email that you click when you're on your way that let's the store know. There are designated parking spots for drive up that uses wifi to notify the store you are there. Otherwise they wouldn't know. Follow the directions in the email telling you your order is ready.
