Yeah,, I looked into vending pellets a bunch of years ago to go along with the coal and firewood. At the time I hauled sawdust for a pellet maker so I would have been backhauling the pellets. My cost FOB the pellet plant was $30/ton less than what the same pellet was retailing for at my competitors 10 miles down the road. Never did get into it as $30/ton to haul,unload,store, and reload didn't trip my trigger.
It would if, you sat on them until the last part of the season and jacked up the per bag price, like everyone else is doing. Then, it's profitable and you aren't gouging 'cause everyone else is.
It's 'supply and demand dictates price'.
My business model is exactly the same for forage products. I run thousands of square bales every summer, chuck them away in the barns and wait until now (or later) to sell them simply because people cannot pre-plan, it's not part of their thought process, so, about this time, they are running low or are out of hay and I can basically charge what I want to (and do), supply and demand.
I'm not gouging, I'm taking advantage of their inability to plan according to projected need.
Of course you need the room for storage (pellets or hay). No issue with mr (hay).
I've considered doing pellets by the truckload and handling it like hay.
