Hmm - I've just seen that postage is $1.55, so >15% of the amount. I'm not sure that is a reasonable fee. I'm deducting $2 from what I'm sending! Lucky there are $2 notes here.

Of course, if not stated I suppose it would be reasonable to assume international bets are are in USD, but it's close enough, and this feels like it's only just holding up anyway.

And most importantly, I think sending $8 is funnier than sending $10.
