I check all that now before buying...I made a mistake on the first couple tanks I bought.
I checked these two, both are full of gas, one is refillable and one isn't. At $7.50 a tank...that's a steal.
I've never paid more than $8.00 per tank, empty or partially full. I have a local guy who will 'top-off' my partial tanks for $1.00 a pound.
I can also refill the one pound Coleman lantern bottles from these tanks...just requires a special fitting.
I've been laying those 16.1 oz. bottles heavy...4-6 per week. I have a few stoves that run on them and a big heating unit that will use them and the 20 pounders.
