What the hell would you ever need a pound of seeds for? making flour!?
There once was a store here in Denver about 15 years ago that sold 1/2lb bags of seeds that had been "Sterilized" so they wouldn't germinate
They were sold to make flour, or for use in baked goods and nothing else...... They were "Hemp" seeds, but regardless most of them would grow, and IIRC that was one of the many reasons they got shut down.
Good luck buying seeds in that kind of bulk unless you are looking in country's that allow industrial hemp, and are looking for industrial hemp seeds.
If you do happen to hit a jackpot and find someone selling medicinal strains by the pound let it be known!!!!!!
