You're fighting human nature.
No one likes to pay shipping, which is why 'Free' Shipping is so popular.
And then if the buyer changes her mind she's shocked at how much shipping actually costs, especially tracked or international tracked.
Even those who paid for tracked shipping as a separate line item, like yours.
I can't really offer more than sympathy.
Are you getting your items back in the same condition you sent them?
Is this an occasional problem?
WalMart says they lose about 1% of their income to 'shoptheft and shrinkage'. Poor comparison in your case, but are you doing better than that?
If it is occasional might I suggest that you can cover these extra costs by using Cookie Jar Insurance, which is just including a small amount as a self-insurance premium on every asking price. Those virtual pennies go in a virtual Cookie Jar and used to cover your costs when you have a problem-- like return postage. No matter what the reason for the return.
If it is more than 1% of your sales, I wonder if this is the problem.
I will not accept returns on the jewelry as it is used vintage with normal signs of wear.
By telling your customer that you will not accept returns, in my opinion, is telling them that the only way they can get a refund is to open a Dispute, rather than contacting you and making polite arrangements.
Although you have such gorgeous stuff, I am amazed that anyone would not want to keep and cherish it.
