Is FedEx the Cheapest of the Three Main Carriers?

When he first started using USPS pickup, I think it threw everyone at the local post office off because the first couple of times nobody showed up. And then they got into the rhythm of it. So no, it's very, very rare that it happens. FedEx has been is the probably the least costly of the three main carriers. There's a zip code thing that can affect it a little bit for lighter weight things. A lot of times, obviously that's going to be cheaper to send through the postal service.
