I see it advertized on Craigs list all the time. Runs anywhere from $50 to $120. Price depends on lots of variables; inside or out side storage, size of bales, quality and type of hay etc.
Better get some bought up @ those prices. Orchard grass, big round, net wrapped bales brought $260/bale on a farm sale & one guy took it all. Western Iowa area. CRP Hay, large rounds, net wrapped $156/bale @ a sale barn venue. Also western Iowa.
