I have an even better version. I rent a small PO box and I keep getting the condo management company's mail meant for the next PO box over. Interestingly enough while informed delivery worked in the pilot program, they kicked it out when it was launched because my box is commercial. So I don't know when mail is inbound and just have to check when I think there's something.

I sometimes only check the box once a month, and it's not uncommon it's full of bill pay checks for people's rent lol.
