I realise this has already been answered, but I did ask about this earlier in the thread, and Rich said the total cost for sending the magnet to the UK was $1.05 postage plus $0.50 for the person to put it in the envelope--so he's still getting a reasonable chunk of the $10 donation, and that's for an international pledge. I suspect he would have pinned that level a bit higher if postage costs were a big issue, as well.
