Ordinarily, when homeowners use gas for cooking, heating, and drying clothing, it's most suitable to have a tank big enough to provide fuel for at least a month's usage, maybe more, without needing to own fuel delivered.
This really is the most cost-efficient means to utilize fuel for home usage as normally it's a bit less expensive if purchased in bulk instead of in smaller quantities that will require more regular shipping.

Most fuel delivery companies ask customers to establish an account relationship with them to ensure regularly scheduled deliveries.
This gives the fuel company a predictable source of income while ensuring that the customer will not run out of propane. Running out of propane creates another service that has to be performed at delivery: the bleeding of the propane delivery line of air.
This action has to be taken when the tank is completely emptied as air in the line will interfere with fuel getting to the appliance. This takes a little extra time for the delivery driver, thus necessitating the need to charge a fee for the service.
This situation is more typical in rural areas as opposed to highly populated urban areas. This extra fee is based on the added cost of sending a delivery truck to an area for only one delivery, so be sure to plan for your delivery needs to avoid running out.
