Western Union transfer from the US to Mexico - bit of information

If you would like to have 800 dollars transferred from your bank in the United States to Mexico and decide to use Western Union here are some facts to consider.
If the current conversion rate is 19.0377 you would expect to receive 15230 pesos, but that is not what happens.
What you actually receive are 14748 pesos, which is approximately 96% of the actual current transfer rate.
Your 800 dollars becomes $774.90 or $25.09 less.
In addition, there is a basic charge by the financial institution sending of approximately 10 US dollars.
So, to finalize it would cost $35.09 ($25.09 + $10.00) to send $800 or $774.90 whichever way you look at it from the United States to Mexico.
I have not made an analysis of how charges are with ATMs but I assume it is "hands up" there too.
