Phew. Thought I was going nuts so Thankyou for letting me know that it is really an issue with the system. But there seems to be no way of raising it with Trade Me or is there a way of doing so that you are aware of?

The only option that came up for me was NZ Post. Aramex wasn’t an option unless there is a button I don’t know about. Next time I will pay more attention. Thanks for input.

Thanks for your ideas and input. I think the prices are based on volume and weight and I definitely inputted correct dimensions for the listing. It is not a rural delivery. Trade me does say that the listing shipping quotes are estimates but I can’t understand why there would be such a hike in price when actually booking the courier. It should be the same as the estimate if the dimension and weight remain the same. But there is no way to contact Trade Me and ask about it.
