What to do with CO2 tank I don't use anymore

[Acco]

I stopped using CO2 in my tank about 5 years ago and I still have the big heavy empty canister sitting around. Can I take it somewhere and get some money back for it or something? What's the proper way to get rid of it?

Thanks!

Sell it.

You can always give it back to the gas supplier.

You only ever really buy the gas anyway, the bottle is kind of a must have. If you have all the co2 kit to go with it why not sell as above.
