My husband and I are hosting an event near Halloween and wanted to do a game giving out gifts that come in pairs (but one per person) and you get either a trick or a treat. So basically a person can pick any gift from the table and will get something terrible/funny or something fun/useful etc. One example would be a box of cookies or a box of dog treats, I found erasers that look like fancy candies so I thought one would be those as the trick and a box of candies for the treat.

They don't have to be food related and $3-$5 is the ideal price range. Any suggestions?
