Spotted the new satchels at local Post Office today.  It appears the same satchel is used for prepaid and postpaid with counter staff adding a prepaid postage label for takeaway.  If you just want postpaid, they sell the same satchel without the label.  Makes sense.

Had a chat with the manager and he was just as confused as his counter staff.  He pointed out the new shelf labels with new prices but they still had the old weight tables printed in the labels !

Their website still shows the old red and white satchels with the new price changes.

I used eBay postage this morning for 500g satchel and was charged the usual $7.55 ?
