Yeah, just to back up the last post. There have been cases where sellers have video footage of buyers picking up their items, whether it is cctv or door bell cameras, etc, yet ebay have not taken it into account when ruling in these cases.  They have been consistent with this, if a buyer makes a claim, the only protection the seller has,  is the successful input of the collection code.

   And yes, too many buyers are playing dumb with regards the collection code, even when they are warned in advance by the seller they need to provide one upon collection. Similarly there are sellers who regard it as excessive / unnecessary by eBay, then complain when they are deceived.
