Finding propane filling locations is hard in Gwinnett County, you pretty much have to deal with Home Depot Blue Rhino exchanges(where you are paying for fuel you aren’t getting) or drive to one of a few locations in the county that you can refill empties. This location was significantly cheaper than the U-Haul in Snellville; we returned today to find them closed(because of the holiday weekend not because it was Sunday). One of the owners happened to be there feeding their guard dog and opened up for us to fill the tanks. Love that kind of service.
