How does Western Union work?

W.U has offices all over the world. They charge a fee for collecting the money at one office and making available to the receiver at another. The receiver must has ID or be able to answer a specific question that only you and the receiver would know. They will also require the receiver to have the MTN ( money transfer number). Last time I checked it was about 100 to send 1000....You could also use a bank wire from your bank to his for much less of a fee
