No signs that I must pay about 5 USD more. It's a bit means, I think
.
You can blame that extra fee on PayPal.
I GOOGLEd and found a
PayPal fees for dummies page that states, "PayPal charges the buyer [
that's you, Mihao] a 2.5% currency conversion fee if he's paying you [
Fastspring.com] in a different currency than you asked for."
So, yes, it's mean. But it's not Amanita Design's fault.
