I got pretty much the same call except I only won 400k and some change. Def a scam

Caller called by the name of John Meyers claiming that I had won $550,000 from the Donald Trump Foundation and all I had to do is go to Radio Shack and buy a green dot scratch off money card for $99 and call him back with the number. He has repeatedly called demanding I get it done today so we could go to the bank before 5:00 to get my check. He also said that him and a few others from readers digest were going to deliver the check to my house. I asked him if I could pickup the check and he said I had to get the card first and call them back with the number. I called the police department and they said it was a scam and that they are using the green dot card to get there money. This call was made on April 2, 2013.
