so ive decided that western uniun would be the best option for me to send money to my son. so now what do i do, im thinking i have to go to a wu and then tell them im sending it to ----- and then also what state and what city or town he is in. then i give them the money, and they give me the 10 digit mtcd. i then call my son and tell him what the control number is, then whenever he gets a chance he can go to the nearest wu, and give them his drivers licance and the control number, and then they will give him the money. is this how it works.
