I recently had a board come from WA by TNT business to business. I recommend it if you are a business .
The board was very well packaged by the sender ( thanks Sandy) but I was impressed by the email transit notification.
I send my paintings via another courier and you have to enter the tracking number in their website to see where it is.
TNT sends out emails at each stage( left depot / in transit/ being delivered - expected delivery time / day etc.)
You can also insure the item .The board came in a pre used board box and I loved the labelling-
no forklift - $ high claim item $
. I was going to start using label that on my portrait packaging but realised my courier only insures for cost of materials which is really helpful when you have a labor intensive product like a painted portrait..
