Thanks to hchaires for posting the new sources for bulk grains to check out.
I thought I'd post the web site Ellen sent me, too, in case others are
interested. She suggested http://www.beanegrains.com/, which has, among other
things, the most extensive listing of whole wheat pastas I've seen anywhere.
I don't yet know how the prices compare to the others', but I will be happy to
report what I find out.
I really appreciate all of you! Thanks again.
