I look at it different in that I am paying for the postage and I charge the buyer a fee to cover this. So by using a service that is $3 cheaper this will allow me to price the item at a higher price. I have never had a buyer ask about tracking and that they are happy to pay the extra amount on a low priced item. I send around 10-20 of these per month which is an extra $500 a year in my pocket instead of Australia Post's.
