Popcorn Maker: Did you know that before there was Jiffy Pop and microwave popcorn people made it by shaking a sauce pan filled with a bit of oil and popcorn kernels? Unless you make popcorn often, you can probably ditch this appliance and never miss it. To get rid of it for free, donate it to a school. Teachers love these for their classrooms because popcorn makes a cheap, fun reward for their hard working kids.
Bread Maker: Kneading bread is good therapy. Ditch this appliance.
Food Processor: These are great because they are so versatile. If you want a big one that does everything like makes pasta, bread, etc. and you know you’ll use it a lot, just make sure it will fit into a cupboard and won’t have to clutter up your counter space. I bought a tiny one at Target (link) for $15.00 and it is all I need. If I need a lot of something I just process twice. It takes up very little space and its parts go right into the dishwasher!
Blender: You don’t really need this if you have a food processor.
