So, you sell say, a $1 paper note value $12 in the shops. You have to charge the buyer the item cost and $7 post pack, $19, to get the label and get the address? No-one will pay $19 for a $12 item. It fits into an envelope, $1.70. But you can't get buyer's address without a label. So what is to stop me printing a label, pay $7, write down the address, cancel the label, $7 will be refunded in a couple of days, pop it in an envelope, pay $1.70 at Australia post?????
