He didn't specify what dollars? AUD? US? Plus, PP says
Pay for goods or services
$0.00 AUD fee. Free for you.
$0 fee
this is an international site, it's pretty much understated that dollars mean US dollars.
It will be $0 fee for you if you Pay For Goods or Service, but he (imsto) will be charged a fee.
So upon payment you should select Gift, so this fee is inflicted upon you instead.
OH MY GOD!
I wait this soooooooooooooooooooooooooo long time and almost die for desperation.
This is all of my FALUT that I haven't logged in here for couple of weeks!!!!!!!
I'll send email to IMSTO even if this is too late.!!!! I'll beg him for this one MY GOODNESS...!!!!!!!!
