Amazon offers the Bob's Red Mill Natural Raw 20-oz. Sunflower Seeds 4-Pack for $8.56. Add it to your cart via Subscribe & Save to cut it to $8.13 and bag free shipping. That's $3 below our June mention and the lowest total price we've seen. (It's also about $6 less than you could expect to pay for this quantity in local stores.)

Be sure to cancel Subscribe & Save after your order ships to avoid being billed for subsequent shipments.
