Propane refill near St. Louis, MO
14 stations that refill your own tank (not just swap it). Posted prices checked September 6, 2026. Sorted cheapest first.
Quick math: a standard 20 lb grill tank holds about 4.7 gallons. At the lowest posted price here ($3.95/gal) a true fill runs about
$18.57 + tax. A swap-cage exchange tank typically comes back with only 15 lb — you pay for gas you don't get.

Other places that refill propane in St. Louis
Many Tractor Supply, Ace Hardware, Costco (members), farm co-ops and independent propane dealers also refill 20–100 lb cylinders and RV tanks. They don't publish live prices online, so we only list stations we can verify. Know one we're missing? Email us the address and we'll check it and add it.
Get a delivered price per gallon in St. Louis
Home tank (100–1,000 gallons)? The per-gallon delivered price is the number that matters, and suppliers rarely post it. Tell us what you need and one local supplier that serves St. Louis will call or email you a price. Free, no obligation, no list — one supplier, one call.
We hand your request to one propane supplier serving your ZIP; they contact you directly. Not sold to lead lists.
Worth having before you go
Three cheap things that pay for themselves on the first refill: a tank gauge so you stop swapping half-full tanks, a 1 lb bottle refill adapter if you run camp stoves or a Buddy heater, and a new 20 lb cylinder if yours is past its 12-year date (the station will refuse it).
Bulk delivery for a home tank is a different service from cylinder refill — get delivery quotes above.
