I got some nice sprouting seeds from:

waltonfeed.com

I was very happy with the seeds and the price.

As I am a Latter Day Saint (Mormon), I have tried sprouting wheat from food storage, but have found that that some of the older seeds do not sprout at all. I always do a small test on any wheat source, to make sure they sprout. I have heard that you can get wheat from feed stores, but I have not done this. I have also sprouted sucessfully wheat from the LDS Canner in Denver that I picked up for about $5 for 25 pounds, other canneries can be found at:

I do not consider myself a "Purest" when it comes to the source of the seeds. I believe you should be able to sprout and also make flour from the same wheat. I am sure, however, that there are various opinions on this matter.

Hope this helps.
