Postage prices unable to be entered prior to selling.

I updated to the newest version of Trade me this morning and was dismayed to find the same problems occurring with postage. I cannot give the buyer a specific cost like we always used to prior to the listing selling. So then it’s a back and forward email to get their address to work out the postage. Sometimes a weird table comes up stating 10.00 for urban, rural or each island that after mucking around finding out the cost you can put it in manually. This system stops buyers paying with Ping as they can’t do an instant payment as they don’t know the postage. I can’t for the life of me see why this would have been changed, surely your IT guys have other problems to fix rather than fixing things that are not broken.
