EcoCard charges $10, then they send the money to another bank that will wire the money to you. That bank charges $20. This is the way it’s been since I started using EcoCard a few months ago.
So, in reality each withdrawal from EcoCard will always cost you at least $30. However, you’ll only see a $10 charge in the EcoCard interface because the other $20 charge happens after the money is out of EcoCard’s hands.
