When I first moved to Knox I didn't have a car but I had a mother and other family I would send packages gifts and greetings to. The Post office was very friendly and helpful with sending me mailing supplies, and deliveries, and even offered to meet me so I could hand them a package, and then picking up my payment from my mail box later. A- 1 service, and I am very appreciative for that.
