I purchase cheap snack-size baggies to fill with trail mixes, because they allow one serving per person. This is easier with children. You can put the mixes into canning jars, but I cannot honestly say if they will stay fresh more than a week. Feel free to try it and let me know.
If you have purchased your pumpkins frugally, you already have the pumpkin seeds that you need. Roast them, flavored for autumn, in the oven at a low temperature.
Pumpkin seeds, roasted with your choice of seasonings
Store brand wheat chex cereal
Store brand raisin bran, or bran flakes and raisins
Store brand pretzels
Candy corn or candy pumpkins, a few per bag
Mix them all together, and and put into baggies or jars.
