Has anybody ever used this method to pay a bill or whtever else it is used for? What I want to know specifically is what is the fee? Does it vary or is it a set fee? I looked at the Western Union online site and of course they don't mention fees or much of anything else about it. They have forms at WU agents along with the others but nothing on there either. Why do these companies need to keep these things so secret?Just wondering if the fees would be much less than regular WU?
