I am having the same problem courier calculated $6.45 Aramex (courier non signature) urban Auckland, however when I book courier after sold the cost is $11.43? The delivery address is not a rural address. This has happened with my last 2x sold auctions both Auckland Urban addresses. Only 2 weeks ago and I was only paying $6.45 Aramex (courier non signature) within urban Auckland. I have been selling a few items lately and I was regularly paying this shipping cost. Is there a problem in the system somethings not right?
