National fulfillment advisors YOU HAVE WON 1,560,000.00 Jackson Heights New York

I received this letter saying I won cash prize of 1,560,000.00. Prize listing no. 01250901964, Prize status ctualized. Notice date 6/2/2016 with deadline date 6/16/16 to send $20.00 and their Documentation acceptance form signed. I could send cash, check, money order payable to NFA. I knew once they asked for cash, to check it out on line and shore enough, others have gotin the same letter. Saying it was a scam. so when in dout, listen to your instantes. I play the publishing clearing house sweepstakes with no one asking to send money, but this has scam written all over it.
