If you buy from Central Milling, they are having a 20% off sale.
"Use coupon YAYSPRING to get 20% OFF 5# bags of Flour & Grains, Merch + Smallwares"
"Online purchases only. Excludes 25 lb. & 50 lb. bags, Mockmill home flour mills, gift certificates, and in-person baking classes. Sale ends Monday, May 19 @ midnight."
I'm not affiliated with Central Milling other than as a customer.
