The other sellers that had this type of item had worse FB, or were located in Sydney.  Actually, if you look around very few sellers have over 87% FB and mots of those with 100% are new accounts.  Yes Melbourne or NZ should mean they are in 2 locations.    And EDD should be irrelevant, IF they indeed post from the listed location, and IF they post within 3 days as stated.  EDD is irrelevant because once the item is posted, it is out of the seller's hands.  Also EDD is often totally wrong.  I bought recently something that had EDD 2nd August and it arrived last week. 

The whole point is that eBay does not care if the sellers use false information in their listing.  As somebody who has been using eBay for both buying and selling for over 20 years, and it used to be my 1st choice when looking for something, I now hardly buy here.  One reason being that even if I search Australia only, or 100km from my place, I still get sellers from China.
