Sometimes, you run across a deal that you just can't pass up: If potatoes go on sale, stock up and dehydrate them. We were grocery shopping one Sunday, and needed to pick up potatoes, which are normally around $2.50 for a 10 pound bag...but then I spied this 25 pound box of potatoes for $2.99, reduced for quick sale. I'm not sure why they needed to sell them quickly, but we snatched them up! And then we had 25 pounds of potatoes. That's a lot of taters.
From deodorant and ketchup, to raising chickens and composting.
