International Postcards!!
 

I just posted a lame-o suggestion for Beergal's fundraiser on another thread, but my research for that led me to this puzzle:

Is there any website/resource out there for gauging international postage rates? I know that some countries' official state sites have them, but it's lucky if those hit on a google search and even luckier if you can start from scratch on the country's home page and find it. Has anyone come across a resource for this?

Usually I save postcards for last on a trip, but it hurts when you're running down to your last native cash (except for the coins you promise to bring home to friends, of course!) and you're just short for the postcards you promised to send!

Dont have an official site, but everywhere i went it was right around a euro.
