Do your kids love Phineas and Ferb? My husband rented the Wii game last week for my son to try out: Phineas and Ferb: Across the 2nd Dimension. He loved it and Amazon has it for $29.99. Great price to get as a Christmas gift and you can get free super saver shipping.
Would you like to buy the movie too? Amazon also has the DVD for $16.99. My kids love getting movies as gifts. That way they have new options for movie night.
