Just a quick video of how I get my new propane tanks when my old ones are out of date. Any one can do this most anywhere there is a propane exchange place in your town or close to U. I got mine at the wally world close to me for $14.48. Then I refill them at Tractor supply that for me is close & the least expensive place $12 to refill them Full 20Lbs not 15Lbs like the exchange tank. Hope this tip helps I have 6 to 8 tanks on hand at all times.
