Pay direct via QIWI or Yandex money.
It will be very simple to pay from Russia!

If they had all the e-wallets from different countries as a payment method, that would obviously be great but I am pretty sure that you understand that it is absolutely impossible. So you'd have to spend some time exchanging the money anyway. But I don't see any problems. These days even mobile load can be cashed out easily with convert pulsa, on http://www.kirimpulsa.com you can check it out.

Right, would be a nice way to make payments. Exchanging money between different wallets isn't really convenient...
