It depends where you live. Bulk items such as beans and wheat are difficult for some of us to obtain.
Here in Tampa there are places which sell bulk beans but Costco is about the cheapest. You can also get crappy bulk rice at Costco (or Sams). Oriental markets sell bulk rice of higher quality.
If you live on the western part of the US you can order wheat and have it shipped fairly cheaply. Here on the east coast it costs $50 for 50lbs of wheat and another $50 for shipping. Except for Honeyville which charges flat rate for your whole shipment.
If you want to buy it already packed for long term storage than you are pretty much stuck paying the hostage rate. I pack my own so I know whats in the bucket.
50 lbs of Homai rice runs around $25 here. Do prices at Costco vary that much regionally?
I’m trying to find a way to prepare it for long-term storage that doesn’t double the price. Ditto beans, oatmeal, yeast, and flour.
