Are you sure this is all the time. I tried to make a withdrawal some time ago and also had the $10 fee placed on my withdrawal (which I didnt make). When I questioned them about it, they said that they charge $10 if you havent funded your account in some time. Thankfully I had only been making withdrawals
After I switched some money around (firepay->party->igmpay->checking->firepay) the $10 withdrawal fee was lifted. Alot of trouble to avoid a $10 fee, but what can I say, I am a cheap bastard!
Maybe this has changed but this may be why you are both seeing this $10 withdrawal fee.
