A town in the middle
Close to plenty. Not close to a shipping counter.
Nolanville sits on the corridor between Belton and Harker Heights, which means a lot is nearby without very much being in town. For shipping that usually leaves two options: the Post Office, or driving somewhere.
The Post Office is genuinely the right answer for a good share of packages — small, light, going to a residential address. It stops being the right answer once a box gets heavy, once something is going overseas, or once a delivery date actually matters. At that point you want to see what the other three carriers would charge for the same box, and that requires a counter that handles all four.
If you are already heading toward Temple for anything else, that is the trip.
