When covid lockdowns hit, our area ran out of seeds and couldn't get shipment. Really hurt some organic small farms here relying on onion and potato sets. I used the organic bags of potatoes from Safeway to grow more. I harvest seeds when I can from my plants. This last fall, I planted a small orchard of apple and cherry trees, a few grape vines, and several blueberry bushes. I have emergency seed packs and trade the varieties I don't want. We have a seed packet exchange at the local library. I buy most of my seeds on ebay from USA sources. Lot of local nursery businesses for plant starts.
