I used to have a hard time finding them but noticed that Lowe's was carrying them this year. Be sure you get the container that is just pure pellets because they do come packaged with something else mixed in - don't recall if its a filler, fertilizer pellets or what now. Will get back later with the name if no one else has come up with it. Incidentally, there is a group that collects these to send to servicemen and women overseas. I spoke with the person a couple of months ago and they are always looking for them.
