I agree with you. The Salvation Army is the one organization you want in case of a problem.
They served hot donuts and coffee to our troops that were sitting on the front line, just a few hundred yards from the German Army. For free.
I’ve worked directly with them in disasters and they are absolutely awe inspiring.
Consider shopping at the Salvation Army stores. I live at the edge of a city bordering on an affluent area. I've found a lot of brand new stuff for my preps including an unused Coleman propane stove and lantern, a new in box Pyromid stove and numerous brand new small electrics and cast iron cooking utensils. My only price is having to listen to one of those "religious" radio stations that supported O'Chavez and thinks all white people are going to hell. On the other hand, it's pretty damned funny.
