I do not pay or charge any fees. I send exactly the amount you request and Western Union will deduct their fee from that.
Most times this is $5 up to $500 and then 1% after that. If the MyWu app is down or Western Union is not working at the stores that process with the MyWu app then I have to use the standard method which is quite costly and is usually $5 up to $50 and then $12.5-50 after that depending on how much is being sent. The $5 fee up to $500 is active for me 95% of the time and should be available when you request to trade with me. So far I haven't seen it matter to which country the money is sent. It seems like WU charges $5 for any country up to $500 when I use my app.
If I get there and it isn't working I'll understand if you don't want to pay a much more costly fee and would rather try again later but it's almost always working just fine.
If you make the trade for $60, I will send $60, you will receive $55
If you make the trade for $500, I will send $500, you will receive $495
If you make the trade for $600, I will send $600, you will receive $594
If you make the trade for $900, I will send $900, you will receive $891
etc.
