Where can I purchase a replacement screen for a RCT6306W87 DWF

I am on a fixed income and it was a gift for my granddaughter and someone accidentally dropped it and I know that it will not be covered under the 1 year Warranty, as it was purchased late part of February 2016. Through Wal-Mart online, I do have the receipt that I can print out as my proof of purchase. She is only 4 years old , but this tablet means everything to here and it is a great device for her learning. I would greatly appreciate anything that you can do for me or let me know as to what or where I can get it fixed for her A.S.A.P. I'm looking to purchase another one and send it to a family member that really doesn't have any tablet or computer, this will be her every first and I know that she will Love it as it is a great devivce . Thank You in advance for your support. Sincerely, Rose M. Sabado / gramy0246@hotmail.com
