Kind of expensive for castings but not toooo bad.  I get I believe 1-1.5 ft^3 bags for like 21 and stuff is typically kind of expensive here.  QUality of castings can have a decent amount of variation

Yeah I dont know the quality but they call it Premium worm castings and something about seeing and smelling you can tell the quality of it the worms are from Canada feeding off of peat moss and leaf something or other
