Propane tanks can be purchased online through the websites of hardware and home improvement stores such as Lowe's, The Home Depot or Ace Hardware. General retail sites such as Amazon also sell various types of propane tanks.
The Lowe's website allows users to filter available listings of propane tanks based on several criteria, including price range and brand. Each listing also contains customer reviews that consist of a one to five star ranking and a written description of the users experience with the product. Once a user has chosen the desired propane tank from the site, she has the ability to choose from three different shipping methods, as of March 2015. Users can choose to have the propane tank delivered to a nearby store or arrange a time to have a Lowe's delivery truck bring the tank directly to the purchaser. Some items can also be shipped by third party parcel post, though this option is not available in all circumstances.
The Home Depot also allows its customers to choose an in-store pickup option on its products, as long as the selected store currently has the item in stock. As Amazon is an online-only retailer, all items purchased through the site must be delivered to the purchaser or to a specially designated Amazon pickup location.
