I accidentally dropped a FedEx-labeled package at my local USPS last Thursday. When I realized my mistake I went to the post office and they said it had probably already been sent to the distribution center by the airport, but that FedEx typically picks up misplaced packages from there. Does anyone know how when/how often those pickups happen? Today would be one week since the error. I have tried finding phone numbers for the FedEx location there with no success (and the general FedEx help line is unsurprisingly unhelpful).
