- ABAngry BunnyOct 31, 20191.0They keep returning mail to sender that is addressed to P.O. box that is paid for. What is the purpose of having a box if post office keeps sending mail back?
- MBMac BroadwayFeb 8, 20194.0The Grant post office is a tasteful, prefab-home style bldg on E Walnut in the heart of Grant. There's a mid-size vestibule open to the public; containing self service area, P.O. Boxes, & an open window above the customer service counter, that's usually secured by a rolling security shutter in similar rural post offices. The facility, inside-n-out, is well kept. 🚗 Lots of parking spaces out front 📮 Loading dock to the side.. 📮 Small but productive. Still getting the job done!
