Mojazz,
I know buckets are easy to get but you have to have food grade plastic.
Many farmers here buy laundry detergent powder in 5 and 6 galloj buckets they later use on the farm but those are not good for storing food in.
The Gamma lids are a bit high priced but the "scew" on and don't wear out like the lids you have to bust open with a lid lifter, with a lifter the lids wear out a lot faster..
Look at the website of "alisonspantry.com". They have some of the same things as Waltonfeed: dried vegetables and storage foods but their prices are a little hugher. They do have the buckets and gamma lids. I buy from a local representative. Their Ghiradelli Dutch pprocess cocoa powder was real real reasonable in 5 lbs packages and so were the Ghiradelli chocolate chips. Most of their merchandise is prepared foods in larger quantities but I don't buy any prepared foods at all. I only ordered the hard white wheat and the chocolate/cocoa and the gamma lids and a few buckets because I already had buckets.. I bet you can find a local rep if you live in Utah, that way they charge only 10% for shipping. Right now they are out of hard white wheat but will have some again from the fresh harvest in a few mionths. It will be a LOT more expensive I am afraid but what can you do?
I did buy 50 lbs of cornmeal from them at $21.00 and shared with two friends, two of us keopt 15 lbs ea and the third person took 20 lbs., worked out real good that way.
I will have to re-order some oxygen absorbers, they come in packages of 100, look like those small envelopes of sugar you used to get in a restaurent, only a bit larger. Maybe you even live close to Alisons Pantry and can shop there. We did spend two winters in St George before it grew so much and really liked it., that was in 80 and 85.We were in an RV park in Washington, right outside of St George and the small park was way at the south end of Washington with a view over the valley, real nice.
The storage foods in Alisons Pantry are called "Rainy Day foods". Grain and flour (from Lehi Mills) is under "baking Supplies)
Let me know how you make out.
