Called everywhere possible within 40 or so miles of STL, ILMO has the cheapest oxygen prices around. Not to mention, John, one of their drivers, is the delivery driver youve always wished you had. Small order or big, John will treat you with respect, and do everything he can to cater to your needs. Ive used 4 different gas providers in the past, but have been with ILMO 3 years now, and never see myself taking my business anywhere else. THIS IS THE GAS COMPANY YOU HAVE BEEN LOOKING FOR!!!
