My thinking is to change all my postage to 5 Business days. On sale I will message buyers within 1 business day the tracking of their posted item. eBay tracking will be updated on the 5th business day (I might need to go 8-9 days). eBay won't protect sellers during slow Australia Post delivery hence creative solutions are needed.
Anyone have another idea for this problem please present it?
Ditch ebay. They have it plastered all over the site that delays are inevitable yet won't support sellers in regard to it. I've stopped selling anything but excess junk.
