Yes John Charmaine is correct. You need the Kroger app when you're ordering & picking up or at least access to the Kruger website. Good luck. I hope you figure it out.
I have never use online grocery with Kroger but I have with Wal-Mart and online they send a message to your phone and you send it back a message that says the time you will be there. When you arrive you send s message that says you are outside. I hope this help.....hopefully your wife let them know you will be picking up the grocery.
