I brought my son a Kindle Fire for Christmas, my daughter dropped it and craked the screen. It was slow charging, so I sent it back to the warranty company. They sent me a gift certifacate, the problem is Toys are Us don't have them in stock. I don't have a 150.00 to but another, I even called others Toys are Us and they don't have them either. They have the HD so what can I do any advice?
