I ususally send one IRC to Europe and two to the US. I always thought this was for "normal" letters in postcard size. I was wondering if it's still the same when I send a bigger envelope. I mean the postage will be more, right? On the other hand it seemed to be no problem with my Ellen Burstyn autograph and one IRC costs 2Euros. When I send two IRCs it makes 4 Euros and that is exactly the postage I have to pay for a "bigger letter" (big photos included) although I know that there is another postage system in the U.S.
You see, I'm rather confused.
It would be very nice if anyone could help me.
