Fanmail.biz

I am in Australia, and I'm planning to send fanmail to London. I've discovered a big problem that's got me stumped. Help would be greatly appreciated.

IRC here have a size restriction. I can only send, and have the receiver send back a post card weighing less than 50g. I can't send a SASE because I am in another country. What do I do?

IRC's can still be redeemed in the UK. They are worth £0.88 each so I would send 2-3 to be safe.
IRC rules in Australia are different to IRC rules in the UK
So you can buy some in Australia, send them to the UK and the celeb can use them to buy return postage to you. Not a problem.
