If you are using a thousand gallons of LP gas per year and you are paying over 50 cents per gallon than what other local suppliers would charge, then you could be spending more than $500 each year. Like all propane customers, you need to keep yourself informed of the supplier's pricing and how it compares with other suppliers in your area. Some suppliers provide monthly payment plans, which can be adjusted to the amount of propane you consume each month and the actual price of the gas. Be sure to keep your account current or up to date with your supplier.
Propane suppliers often charge customers per gallon. If a supplier claims low prices in its advertisements, be sure to do your homework before you believe any word of it. Request a price quote per gallon price prior to every delivery. Shop around and compare suppliers to find the best price where possible.
Part of your responsibility in monitoring the current propane prices is learning about the prices of crude oil. Apart from being a by-product of natural gas processing, propane is produced from crude oil refining, too. Hence, the prices of crude oil may affect the price that you would have to pay for propane, too. You should be able to learn the status of the crude oil market online, by watching the news, or in the newspapers.
