And to consider a $13.40 satchel it actually costs you $15.80 to post it.
If you offer free postage for it you are $15.80 out of pocket.
I sell a lot of items in the $10.00 to $35.00 price range and there is not enough profit in these items to offer free postage.
And if you send without tracking the incidence of false claims and losses is significant now adays.
