I have 2 sets of the Tag Reading system for kids. Either buy one set for $25 or buy both for $40. One is purple and the other is green. It comes with the install CD to access it on the computer. It comes with a parents guide to get it started. I have 9 books that go with them. They are: Star Wars, Click clack Moo Cows that type, Ariels adventures, Disney's Up, Olivia, Tinker Bell, Toy story 3, Kunfu Panda, and Diego. It will keep your pre readers entertained for hours.
