Two special offers are out there:
1. Now through November, 4, KAF is having free shipping on all parchment products.
2. Bob's Red Mill is having a 20% off sale, beginning November 4. I'm not sure if you have to be signed up for their emails to get the code, or if it will be available on the website. In addition to flours, they have beans, rice, and various whole grains. They always have free shipping on $50 or more, but 25 pound bags do not count. Cases of smaller products do.
