Our buy-nothing plan has kind of slipped, but we're going to try again.
I've been making popcorn in a pot on the stove. It hasn't worked very well. Lots of kernels were not getting popped completely, making it hard on our teeth. I thought maybe it was the cheap bulk popcorn, so I bought a jar of Orville Redenbacher popcorn. On the same shopping trip I stopped at the Goodwill to see if I might luck out and find an air popper. Score! I found one that looked like it was in good shape and clean, but it was missing the cup on top. I figured I could come up with something to plug the hole. It was $6.99. I also noticed a Hamilton Beach food processor, also in good shape, for $9.99. When I got to the checkout I learned that the popcorn popper was half price. So I got both for $13.50. I've tried the popper already, and it works great, even on the cheap popcorn. I have yet to use the food processor, but it appears to work fine.
