I don't know how much the super sack weighs. I will have to ask next weekend.
Either super sack or 40 lb bags, the stuff is delivered by truck. I'ts cheaper if one has a fork lift to off load- otherwise there is about a $300.00 extra charge for a lift-gate truck. I know it was a priority for the organization to get a fork lift to avoid that extra charge.
I think the stuff comes straight from the pellet mill, but I am not directly involved in procurement so I don't know all the details.
