Are you in the US? Find a local UPS Store that does package acceptance. You can mail/ship to that store and they will hold if for you. It cost $5 to pick it up. I have done this several times without issue. I just email the store and let them know I am expecting a package before it gets there. Note, not all UPS Stores offer this service.
I’m sure anywhere will ship to a po box
