I work at Arrow Seed Company in Central NE and we have Winter Rye priced at 10.50/56# Bag (1 bushel bags) and a wide variety of winter wheat starting at 10.50/50# Bag. We also carry a wide selection of other small grains. We deal with everything but Corn and Soybeans.
It's the old "Bulk" pricing as opposed to convenience pricing. I couldn't get mine to break a bag and sell it by the pound so I bought the whole 50 as well. Looks like I am going to have turnips EVERYWHERE...if it ever rains
