priority mail box reuse


Is it possible to reuse the priority shipping boxes that I received from another shipment to ship to someone else?
I would think they could be reused as long as the address' are removed and recovered as well as the previous tracking number. You will be paying the priority rate though on the next shipment. I know you cant use a Priority box without paying priority shipping rate.
I do it at work all the time. I've been known to put stuff in a USPS box and ship it UPS/FedEx. They don't care as long as the label is correct on where it is going. I also ship Bowtech bows back to the factory in PSE boxes.....:D
