I find it amusing that people think that with the RBA banning these surcharges, that they will pay less than they do currently for those goods or services.
The price will just change to incorporate what the business was used to taking in - maybe even a little higher, after rounding - and other than deciding to buy elsewhere (who would
also have increased their prices), there is nothing you can do about it. It’s just a waste of time, and taxes… again.
At least you’ll be able to marry up the cost on the sticker with the cost on your statement though
