Although the site is down for me. Is this a usual occurrence?
Sorry, try this:
https://visa.qiwi.com/ or
https://qiwi.com/ without WWW.
They are just preparing their website to serve western users, so they may have small issues like this, but the QIWI payment system is operate very good for me.
What is the total amount of fees from Credit Card > Qiwi > BTC-E?
Too much. They also don't accept online credit cards, they accept credit cards from certain terminals in Eastern Europe
You could try bank card, dunno if it works with N. American networks
https://visa.qiwi.com/card/replenish.action?paymentModeType=CARD but keep in mind giant Interkassa fees.
