You guys are reminding me of stuff I have stored away that I really don't use. Out of sight, out of mind I guess.
cookie press, used once
fill n bake pan, used once
pancake flipper pan, thingy, haven't used in 2 years
angel food cake tube pan, used once
tart pan, never used
2 mini muffin pans, used very few times
tart shaper for the mini muffin pan (pampered chef), used once
2 in 1 food processor/blender, used each once (like my big food processor better)
deep fryer, used once, loved my old fry baby, but it was ancient and died, I'd love a fry daddy. I don't fry often, but loved it for when I did.
I'm sure there are plenty more that I'll think of as other people mention them!
