You're correct I have not read the numerous threads about it. At what point did I say I wished to opt out? My original question which nobody has been able to answer was around whether the confirmation that an item has been received by Big W / Woolies track or otherwise is usable in a not received case.  There has been no definititve answer to that question and I am more than aware that untracked is untracked.  Do you actually know the answer Dave? If not no worries have a lovely day 🙂

eBay C&C rules say that once a buyer is notified that the item is ready to pick up at the store, the item is considered delivered, the seller's role has finished and the buyer can no longer claim not received.  If the buyer fails to collect, the item is returned to the seller and if the buyer wants it resent they need to pay for a second delivery.

From what I read, tracking is recommended not mandatory and dispatch can be up to 10 days, recommended 0-3.
