I am not sure about price, but I get mine at the local Lowe's or Home Depot in the paint area.
You can store it in just about anything...I have used aluminum fuel bottles, the Nalgene fuel bottle(mentioned in next post) but I think my favorite is just the plain old 20 oz pop bottle. Light weight, disposable and 20 oz of denatured alcohol would run a pop can stove for several weeks if you were just boiling cups of water at a time for meals or purification.
