Has anyone recieved one of those "prayer rugs" from Saint Matthew's Church?

I got a "prayer rug" in the mail from a Saint Matthew's Church. I'm suppose to pray on it, stick it in the Bible overnight, then send it back with some prayer reqests. After I do that I'm suppose to open up this "prophesy" they sent me. Surprisingly, they don't really ask for money (because as soon as I saw it in the mail I though it was some rip-off). Does anyone know anything about it? It's not some satanic organization posing as a church to get you to pray on a rug and then they do some voo doo stuff with it, or is it?
