I've never used the labels. Take your stuff to the P.O. It gives someone a job & cuts eBay out from gleaning more profit with the deal they've no doubt cut with Aust Post. They already take 7-10% on postage.  Plus they've probably raked in loads of $ from this so-called 'glitch' that most sellers wouldn't notice (or be bothered following up on). I buy my satchels from the post office in packs of 10 & get 10% discount anywway.
