Have you ever wanted a glass, that stops messy accidents before they happen, or pants, that provide relief at the touch of a button? In But Wait, There's More!, players pitch wacky products to each other for fun and profit.

At the start of the game, each player receives three "Feature" cards. Each round starts with one Product card being revealed from the deck, e.g., guitar. Each player in turn has thirty seconds to play one of their Feature cards – say, "Helps you fall asleep and stay asleep" – and pitch their own version of a guitar. At some point during these thirty seconds, this player must say, "But wait, there's more!", then reveal the top Feature card from the deck – say, "great for parties" – and incorporate that Feature into their product. Once all players have pitched their unique version of a guitar, everyone votes simultaneously for which pitches they liked the best. The top vote getter after three rounds wins the game!

With six or more people, play in teams, with the first player on a team starting the pitch with one of his Feature cards and the second player finishing the pitch with a Feature card of her own, but neither player knows what the other Feature is until they are revealed!
