I noticed the new fee this week as well.
I have been using MG for a year or so. I started when I noticed the Zero transfer fee + to virtual wallet + the speed of instant transfer when using US debit card instead of from bank ACH transfer. Only do once every month two with a few hundred USD.
Even though the XE rate is always lower than WU, the total cost for amount received is better with MG when factoring in the huge WU fee. Still better even when asked WU customer service for a 50% off fee promo.
What I see now is $7 MG fee though then they show a promo which knocks it down to $4, when using Debit card. If from ACH bank transfer then only $1.99 which I remember sometimes was slow. I have not done the math, but I expect it will still be slightly better than WU. Looks like they are trying to implement a frequent flyer type system where you gain points toward discounts on your next transfer.
