No you dont get fee's if you send as a gift, Well, Then dont, Depending on the amount your sending you may be liable to take the fees for the other person,
It does, but not every time. I don't know for sure what causes it, but i once sent a payment of around $30 or less and it charged me an extra ...say... $0.50? I did about a dozen other payments for $5-30 also, though, and none of them charged anything. So idk.
