What are some ideas for game prizes! Need to know ASAP!?

Okay, so I'm going to be going to my cousins house tomorrow! I am staying for two weeks. We are planning to have a skeeball championship, some poker, mini golf tournament, board games, etc. I need some ideas for prizes, such as a small candy. Keep the ideas PG, and we will not play for money. Try to be specific; "Play for food" isn't going to help me lots. Try suggesting a specific type of food. Try to think of something that can be purchased at a dollar store, or is real cheap....not buying any cars.
