I get mine loose from the local feed guy, I just take 5 old feed feed backs and we shovle it in, £20 in his top pocket! Store it in a cleaned out wheelie bin, feed it in a trough. Works out cheaper. I don't use loads, only have 4 to 6 weaners at a time. Don't know if every feed supplier would be happy with the arangement but I suspect he dosen't but the £20 through the books and its just a bit of pocket money!
