Except ... "As part of our product standardisation, Prepaid Express Post 3kg large and Express Post 5kg large satchels will be withdrawn from 8 April 2013. However, if you have purchased prepaid Express Post 3kg large and 5kg large satchels, you can continue to lodge these parcels." It seems that only the 500g Express Post satchels will remain?? BTW, I don't understand your statement that Express Post satchels have a "slower delivery time" than Platinum Express? My understanding it's the same delivery network for both Express Post and Platinum Express Post with "next business day" delivery, so how can it be slower?
