I got a 8lb keg at sportsmans a few months ago for $340, im not sure why it was cheaper then, but it was a whole lot better than that, so I bought it.
Damn, that was a good snag!! The main thing is at least we are starting to see it on the shelves again. I still have quite a bit of the 10 pounds I bought 2 years ago, but have not been burning it up like i used to, since it's been unobtanium.
