Just got my 5# tank filled at Airgas. Cost was $24.33 before tax ($26.28 after tax).
I did find one thing interesting...while ringing me up the guy made a casual comment about how the CO2 must be coming from somewhere else because the cost had gone up. I laughed and mentioned to him how I pay something different every time I come in it seems. He stated that they have a plant in Augusta, GA (reference: I'm in SC, about an hour and change from Augusta) that they manufacture their CO2 at. But if they have to get it from somewhere else, the midwest for example, the cost goes up. So frustrating.
Not to mention I now have to figure out why I'm leaking gas at the connection of the regulator to the tank. It was fine two days ago...
