I can send a standard, up to 20mm thick, book for $2.30 using prepaid envelopes. They are good for 500g and buying them in 50s gets that price. Admittedly very few books that thick mass over 250g, so the saving isn't huge.
That 5% discount is all Australia Post gives for bulk purchases these days. Even prepaid satchels, which they used to give a 10% discount for if you bought 100.
For parcels, volume discounts apply through MyPost Business if you have the volume.
You might sneak the odd one through, but if you get pinged you will be charged the difference between what you paid and what you should have paid, plus $1.50 admin fee. If you don't have a return address your buyer will get hit with the charges. You don't need too many unhappy buyers before it impacts on your selling.
In the long run you have to decide whether or not your items are competitive paying the correct rates.
Even with a return address, I have had Auspost charge a customer on more than one occasion. I assume they do it so that they get the money rather than it going to head office in the form of a bill payment.
