This is a scam.  I was speaking with a lady by the name of Jamie Gray.  Once the check is deposited or cashed you are asked to purchase a Green Dot Money Pak from Walmart for the amount of taxes you will be responsible for paying on the winnings at the end of the year.  Supposedly this is to insure Dana App Inc. that the tax money was indeed set aside so that there is no audit issues on their end.  They stress very convincingly that no one can do anything with this Money Pak Card as long as the Money Pak Number has not been scratched off of the back of it, which is true, however, they require you to then call them and give them information off of the receipt to prove that you did purchase the Money Pak, such as the teller number, first four digits of the bar code and the activation number then they will Fed Ex the remainder of the winnings to you at no charge.  What you do not know at the time is the activiation number on the Wal-Mart receipt is the Money Pak Number but you do not know this until you scratch off the back of the Money Pak Card.  They get your money the same day you give them the activiation number.
