Looking for Gaz C206 cartridges

Does anyone have a source for gaz C206 cartridges? I live in Kansas City.

Thanks in advance,

REI sells these, at least they do at the stores in the Twin Cities, although the canisters are not on the REI web site. Mail ordering the canisters is frequently expensive as most shippers want to charge a hazmat fee. You can ship gas canisters parcel post, if you lable the box properly, and there is no additional fee from the post office.
