Between 2.25 and 2.75
This is a difficult question to answer. Are you talking about just getting small bottles filled? You can expect to pay between $2.00 and $3.00 per gallon depending where you go. Is it for residential? The bigger the tank the better the price. Example: 500 gallon tank this time of year (November) can range between $1.75 and $2.00 per gallon. Is it a commercial set up? Again, depending on tank size and usage you can expect to pay between $1.30 and $1.50 per gallon. Hopefully this helps.
