Propane prices vary more than most people realize — sometimes by more than $2.00 per gallon between a retail exchange cage and a local refill dealer just a few miles away. If you're filling a 20-lb grill tank a handful of times a year, those differences add up fast. Here's exactly how to find the cheapest propane near you and what to expect to pay in Texas and New Mexico in 2026.

What Does Propane Cost Per Gallon Right Now?

Propane is priced by the gallon, but the rate you pay depends heavily on where and how you buy it. Here are the three main options and what each costs in 2026:

The takeaway: cylinder refills at a local dealer give you the best value for small tanks. Bulk delivery is cheaper per gallon for homeowners with large fixed tanks. Exchange programs are the most expensive option on a per-gallon basis.

Refill vs. Exchange: The Real Price Gap

Exchange programs like Blue Rhino and AmeriGas are everywhere — Walmart, Home Depot, most grocery stores and gas stations. They're convenient, but they silently cost you in two ways:

• Less propane per fill: Exchange tanks are filled to only 15 lbs, not the full 20-lb capacity of your cylinder. You're paying for a full-looking tank but leaving ~25% of its capacity empty.
• Higher per-gallon rate: At $24–$30 per swap for 3.5 gallons, exchange works out to about $5.00/gallon — versus $3.25–$4.00/gallon at a local refill station.

On a single fill, refilling saves you $7–$12. Over a full year of grilling and outdoor heating use — say five fills — that's $35–$60 back in your pocket for zero extra effort beyond driving to a different spot.

Where to Find the Cheapest Propane Stations

Not all refill stations are equally priced. Here's where to look, ranked roughly from cheapest to most expensive:

1. Independent propane dealers: Local dealers typically offer the lowest per-gallon rates because they have lower overhead than national chains. Many also do bulk residential delivery.
2. Farm and ranch supply stores: Tractor Supply Co. and similar stores often post competitive refill pricing. Their stations are reliable and staffed during store hours.
3. U-Haul locations: U-Haul offers propane refills at many locations and is generally priced below the national exchange programs.
4. RV dealerships and campgrounds: These cater to customers who depend on propane and usually offer fair prices to attract repeat business.
5. National chain refill stations (Ferrellgas, Suburban Propane): Competitively priced but slightly more than independent dealers on average.
6. Retail exchange cages (Blue Rhino, AmeriGas): Highest effective cost per gallon. Best reserved for emergencies or when convenience outweighs cost.

7 Proven Ways to Pay Less for Propane

1. Call Ahead and Compare Prices

Propane prices move with the energy market and can shift week to week. Spend two minutes calling two or three stations near you and asking their current per-gallon refill rate. A quick call before a trip can save you several dollars.

2. Fill in Spring or Summer

Propane demand peaks in winter when households rely on it for heating. Prices are typically at their lowest in April through August. If you own a large residential tank or use propane heavily, filling up in summer versus winter can save $0.25–$0.75 per gallon.

3. Fill Your Tank Before It's Completely Empty

Running out entirely often means an emergency fill — which dealers sometimes charge a premium for, especially on weekends or evenings. Keeping track of your level and refilling when you still have some propane left lets you shop around on your own schedule.

4. Ask About Price-Lock or Pre-Buy Programs

Many residential propane dealers offer pre-buy contracts where you lock in a per-gallon price before winter. If you expect to use a lot of propane, this can protect you from seasonal price spikes. Ask your local dealer in September or October before the heating season begins.

5. Negotiate as a Loyal Customer

Independent dealers have more pricing flexibility than national chains. If you've been buying from the same place for years, it's reasonable to ask for a discount. A simple "I've been a regular customer — do you have any loyalty pricing?" often works better than people expect.

6. Join a Co-op or Buying Group

In rural areas of Texas and New Mexico, agricultural co-ops often sell propane to members at below-market rates. If you're eligible for a farm bureau or rural electric co-op membership, check whether they offer propane at a member discount.

7. Keep Your Equipment Efficient

A well-maintained grill, heater, or appliance burns propane more efficiently. Clean burner ports regularly, check for leaks at connections, and replace worn regulator hoses. A leaking or inefficient appliance can add 10–20% to your propane consumption without you noticing.

How to Check Your Propane Level Before You Go

Knowing roughly how much propane you have left helps you plan fills before an emergency. Three quick methods:

• The warm water trick: Pour warm (not boiling) water down the side of the tank. Run your hand along the metal — the level where it shifts from warm to cool is approximately where the propane surface is.
• Weigh it: Most 20-lb cylinders weigh 17–18 lbs empty (check the tare weight stamped on the collar). Weigh your tank and subtract the tare weight — the remainder is how many pounds of propane remain.
• Inline gauge: An aftermarket inline gauge ($10–$20) screws between the tank valve and your regulator hose and gives a real-time color-coded reading.

Frequently Asked Questions

What is the cheapest way to get propane?

Refilling your existing cylinder at a local propane dealer is almost always the cheapest option. You pay by the gallon for a full 20-lb fill at $3.00–$4.50/gal — compared to $4.80–$5.50/gal effective cost through exchange programs that only fill to 15 lbs. Per fill, you save $7–$12 by choosing refill over exchange.

When is propane cheapest to buy?

Late spring through summer (April–August) is when propane prices are typically at their seasonal low. Heating demand drops, wholesale costs ease, and most dealers pass some savings along. Prices rise in October–February when winter demand peaks. If you can time a large fill for summer, you'll pay less per gallon.

Can I negotiate propane prices?

Yes, especially with independent dealers for residential delivery. Mentioning a competitor's lower quote, asking about a loyalty discount, or inquiring about a price-lock contract before winter are all reasonable conversations. For small cylinder refills at posted rates, prices are usually fixed — but it never hurts to ask.

Is propane cheaper in Texas than in New Mexico?

Marginally, in most cases. Texas has more propane infrastructure and competition, which keeps prices at the lower end of the range. New Mexico, particularly in smaller markets like Santa Fe, tends to run slightly higher. The difference is typically $0.25–$0.50 per gallon for equivalent service types.

The Bottom Line

The single biggest way to pay less for propane is to skip the exchange cage and find a local refill station. Beyond that, timing your fills for spring and summer, calling ahead to compare prices, and building a relationship with an independent dealer are the strategies that consistently save money over time.
