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. 

Yes anything to save a $1 nowadays,  but for mine,  postage set at say  $15 for most items, postage cost + ebay fee.  The buyer pays up front, I then process via My post business, at discounted rates, so the discount becomes pure profit.

No worries about INR and scam buyers simply claiming I have not got it, because it is known worldwide, no tracking its free, any such claim is now against ebay, not me.

My low valued items are usually around the $10 mark and the postage $3. I would rather not sell items at this price range but over a year they add up.
