San Antonio Express-News, Price: $100.00, This item was barely used. I have many cartridges/books on different subjects from letters/sounds, math and numbers, colors and shapes and beginning reading. It also includes an extra writing pencil and case for all components. It runs on 4 AA batteries. This is perfect for children in pre-k to First grade. This is a great deal as each cartridge/book can run $25 each. If you have any questions or would like more pics, call/email me at 210-782-7338.
