Hi Chad, Compressed Gas Western 4535 W Marginal Way SW Seattle, WA 98106 (206) 935-5093 They will fill your own tank while you wait; a 20# used to be $20.25 plus hazmat and sales tax probably about $25. I always call first and make sure a technician is there so they will be able to do it while I wait. Hope this helps.
