Try to control costs. Don't know what I would do with the extra if I bought a full roll. Actually, I could get by with two 15' pieces and a couple smaller ones in the 6-8' range. As long it is O2 barrier and will accept regular barbed pex fitting it should work for me. I can't find anything local and will have to order anyway. If you have something you want to unload reply or send a PM.
