if i recall correctly it also calculates into your currency once you log into paypal to pay. or just google it. or learn to do rough calculations of conversion of common currencies.
like 1 euro ~= 1.5 usd
And as frank said, each bank uses different conversion rates and updates them at different times which can actually change price quite enough to piss some people off with "inaccurate" prices.
Like when i went to germany with my gf to visit her parents (who are usaf and live on base), i would give her dad money to convert for me as he got super awesome military usd -> euro conversion rates that beat the heck out of the normal bank rates.
also if you wont pay for bits and bytes? ok.. go make those bits and bytes yourself.
You paid for your computer yes? that means money most likely went towards microsoft's os (bits/bytes). And work is work. The knowledge to make bits/bytes
is expensive and takes a long time to gain sometimes. What about any games/cds?
Would you pay for a product made of wood? you have trees right outside for free... Would you pay for food? you could grow your own....
Digital products are worth a price just like everything else.
