No, no. Say you are in Germany, and you want to mail cards to 25 American addresses. But she posted that it would cost 1,53 Euro each, so that times 25 would be $38,25 Euros! But if she put them all in one big envelope and sent them say, to me, it might cost her 3,00 Euros because it would be a bigger envelope (just guessing) but then it would cost just an additional $9.25 US to send them out once they got to the US, so (if we're pretending 1 Euro = $1 just for simplicities sake) she'd save $26 and still reach 25 people.

Did that make it more confusing or less confusing?
