I have several used propane tanks for sale.
These are the 20 lb. size that are oftern called barbecue size.
It is the standard size that can be exchanged at Wal-Mart, Lowe's, Kroger, Fiesta,
your local barbecue store and probably Ace Hardware among others.
They can also be refilled at your local propane dealer at about half the price of exchanging it.
If you have a new house or a new grill or other device, you will love having an extra tank.
As I said I have several tanks but I don't have a picture. If you need one you probably know what a propane tank looks like.
Thank you for looking
