CO2 refills in Utah County
Places I have found for refilling CO2 in Utah County:
(None of the prices include sales tax, and may change at any time)
Praxair, 1211 S Industrial Parkway. $25 for 5lb co2 tank, $25 for 10lb, exchange only.
Field Welding Supply, 502 S 300 W. $21 for 5lb, $26.95 for 10lb, exchange only.
US Welding, 60 S. 1500 W. $25 for 5lb co2 tank, $27-ish for 10lb, exchnage only.
Humphries, 34 East Main street. $10-ish for 2.5lb, $15-ish for 5lb, can exchange or leave your tank for refill. They refill on Thursdays (I think).
Humphries takes the cake for the cheapest co2 tank refills (that aren't paintball tanks).
Paintball CO2 refills:
Sports Authority, Provo: $3.50 for 24oz tank.
Saints Paintball, Provo: 20 cents per ounce.
Dick's, Orem, University Parkway, $4 for 24oz tank.
For paintball tanks, it looks like Sports Authority is the cheapest.
Just thought you'd like to know - it took me days of calling around to find out all these numbers.
