Picking up items takes too long mostly because of the long pick up code you assign.
I want to see the email confirmation come with a QR Code, or something, that can easily be scanned at the register instead of the associate trying to read the long random Order # from the phone while also keeping it lit bright enough.
Think of the possibilties of this. Your store can use it to identify the picked order and even the box its in.
Also how about when scanned, can tell the customer the realtime status of the order (because your emails 1/3 of the time end up in my spam).
I used store pickup at least twice a month and this is the only part that I hate about the process and I don't want to waste paper and ink printing the email.
