Dont worry, I feel your pain, but as already mentioned, without tracking, there is nothing ebay can do to confirm it has been delivered.

Most items I sell are untracked, and getting a INR is a risk I take and something I have to deal with, as most of my competitors also sell untracked, so to compete i need to do the same.

I agree, some buyers do exploit this, knowing the item is not tracked and therefore you cant confirm it has been delivered. But also i would like to think most a genuine, and AusPost does loose items, we have even had tracked items lost.

But at this time especially, the INR period should be extended, so buyers cannot file them almost immediately after the item is posted.

And because of this reason, just today I have increased all my postage prices to include tracking, it will still be late, but at least I have proof of tracking now, it will loose me many customers, but i'd rather that than a headache.

Everyone stay safe and take care out there.
