For people looking for whole wheat flour, Bob's Red Mill has 5 lb. bags available (limit 2). That does not include shipping. I have paid $9.99 shipping (quick with UPS ground), which seems to be a flat fee, as I included a couple of other items in the two orders I've done.

I don't know how long it will be available. I'm posting at 12:25 p.m. eastern time.
