Update: they finally replied back AND made payment, so all is good.   Thanks for your help all.

Why is Ping Surcharging on Shipping? I never understood that as shipping problems are handled by the courier company/NZPost. So why is Trademe taking a cut? If we're paying a fee then we should be able to claim from Trademe and Courier when shipping goes wrong (damaged/lost)

When a auction ends and you can do fixed price offer, you can see/select who to offer it to, Obviously the person who bought it was one of the people who was watching it that I can offer to.
