I needed some propane , so I called the closest place to get a price on a 30 lbs. tank of propane and the guy on the other end of the phone quoted me that it would be $25.00 so I went in the very next day and the mgr. of precision oxygen said it was $28.00 . So I told him about the phone call I made and the quoted price of $25.00 and then he got very rude........ enough said ...... CUSTOMER SERVICE IS VERY UNDESIRABLE NO STARS >>>>>
