- JSJason SmuckerJul 18, 20261.0I Sent my son to pick up some straw bales, guess I should have checked price first -$25/ bale 🤯 I should have sent him to miller feed and get them for $6/Bale but was in a hurry and knew they would be more expensive but not that crazy!. I had stopped buying other supplies from there because everything is 20-30% more than anywhere else, guess that is what happens when a big corporation takes over a small company. Never going there again.
