Best Buy offers the Disney Infinity Phineas and Ferb Toy Box Set for $10.99. Opt for in-store pickup to avoid the $2.99 shipping charge. (Update: Shipping is no longer available.) That's $20 below our December mention and the lowest total price we've seen. (It's a current low by $15.) This set is compatible with PlayStation 3, Xbox 360, Nintendo Wii, Wii U, and 3DS.
