Candy Grams were invitations to the Valentine's Day Dance in The Third Wheel. They costed 25¢ (cents). They were sold by the Dance Committee. A lot of kids wanted them and they seemed to be important to buy, mostly to get invite people as a "date" to the Valentine's Day Dance. Greg tried something different after asking a few people out, which was buying Candy Grams that were delivered to him, to make it appear that lots of people wanted him as their "date" to make him seem popular so people might actually invite him as their "date".
