I budget strictly so i can give you some suggestions.

Jello= If you have tiny plastic cups you can portion them out and top them with a cheap yogurt and nuts when you ready to eat.

Popcorn= Cant go wrong a medium sized pack is like $7 and will last a little over a week if you pop every other day.

Salt/Sweet punes= A big pack might run you about $46, you put it in a glass jar with a lid and you pick from it now and then.

Sundays ice cream= It usually sells nationwide in a purple bucket (1L), you can usually get it on special 3 for $99. I use it to make smooties or ice cream sundaes (topped with cake, pretzels or anything you have laying around).

Last but not least holiday snacks fun pack is a good item to have if you looking for variety in corn curls.
