Anyone who has kids, particularly preschoolers, all the Putt-Putt educational games are on sale for $.99 a piece (usually $4.99).
My kids loved the PC versions when they were that age. And they're more tolerable and semi-fun to play with them compared to other educational software.
Edit: Figured out why the sale is going on. There's a Humongous Entertainment Humble Bundle for Android, which also includes some Spy Fox, Pajama Sam and Freddi Fish games. All good stuff for the little ones if you have an Android.
