Buying Time

Does anyone out there have the the most updated pricelist on "time"? I've just bought me some much needed extra of that particular item, and I have a strong feeling that the end cost will be enormous. I don't even know the currency. Dollar? Yen? My soul? Or perhaps some peculiar form of payment, yet unknown? Sometimes the fineprint at the end of a contract is so small you can't see it, but there usually is a catch.

Catch me, if you can...
