CO2 supply in Greensboro
Probably should have started this thread before I went out and found a tank, but I ended up buying a 5# tank at Arigas National Welding in Greensboro (east-central GSO) for about $65. 20# was about $120. Swaps for 5# are $17, and 20# are $32.
They also stock Victor regulators.
Robert's Oxygen (far western GSO): $12 per 5# swaps, and $18 per 20# swaps. They don't have 10# cylinders. About $140 for a 20# aluminum cylinder, and a dollar or two less for steel.
Carolina Carbonic & Hydro (central GSO) does refills. $25 regardless of size for the first, and $21 for the next however many. So 3 tanks, a 5, 10, and 20 (for example) would cost $25+21+21.
Fifth Season Gardening (north central GSO): swaps, $22 for either a 5# or 20#. They only keep two of each on hand.
