I haven't reached the point yet where I'm personally dumpster diving, but I have a friend who has an inside connection at a major grocery store. They call when it's time to take out the garbage, set it outside the compactor, and my friend swings by to snag it. It's incredible how much gets thrown out. He preserves what can't be used immediately and gives it away to those who don't have a problem with the source. I've benefited from a 5 lb bag of jerky and a box full of dried fruits, veggies, and other items.

Otherwise, I'm always on the lookout for sales and deals. When I find one I stock up, like the one going on now at Amazon for Sweet Sue canned chicken that worked out to 78 cents for a 5oz can.

I'm fortunate enough to have a few acres and access to water at agricultural rates, so I grow enough produce to supply myself and a few other families that subscribe to my farm-to-home service. It's enough to pay the costs and buy the grandkids some nice presents, but I ain't getting rich off it.
