I always buy my wheat from the Home Storage Centers of the Church of Jesus Christ of Latter-day Saints, the Mormons. You don't have to be Mormon to buy wheat there. The Home Storage Centers are run by volunteers so you do need to call ahead and see when the center will be open before going.
Home Storage Centers are all over the United States and Canada. Here is a map of the different locations.
- Locate the Home Storage Center closest to you.
- Then call the friendly people at the number listed.
- Let them know that you would like to come buy a 25 pound bag of wheat.
- Ask when they are open.
- If they ask what ward you are in, tell them you are not Mormon but would like to buy some wheat.
The current price for 25 pounds or hard white wheat or hard red wheat is $11.45. Look on the order form on the right hand side under the bulk column to see the prices.
And if you need more info on packaging and storing wheat for long-term use providentliving.org has lots of information.
