No mouse just bought a used vtech nitro notebook but it didn't come with a mouse or a box where can I buy a mouse for it

You should be able to buy a mouse at any local electronics store like Best Buy, Circuit City, RadioShack, etc. You would connect it through one of your USB ports on your notebook.

You can find a few replacement parts for the Vtec Nitro Notebook for free at this page including a mouse. Problem is the mouse is out of stock at this time. Keep trying. I am. http://www.vtechkids.com/support_replacement_detail.cfm?productID=291
