We are shipping about 300 to 500 packages a day with USPS right now, most between 10 oz and 5 lbs. We have scheduled a pickup, but they keep sending a tiny truck that is already at least half full and saying they will either come back later or that they can't come back at all. Out of desperation we are making multiple trips to our local post office, and got fussed at yesterday for not sorting first class mail from priority mail. Who knew? Anyway, we really need to change the game here to get through Q4.
My question is: What are other high volume sellers doing to ship hundreds of packages via USPS daily?
