Heh, I didn't know My Products existed until you mentioned it - this could be why I'm guessing. All sales to date have purely been through the basic Trademe business profile we operate. I'll have a titu around in My Products - might answer my own question.....thanks for your help.

Thank you for the detailed reply. Unfortunately on my account this isn't an option provided. 

Dear Trademe, I'm not sure if it is possible but if it is, are you able to update your courier booking service so multiple packages to the same customer can be booked at once? Our business often sends multiple packages to the same customer and it gets a bit dreary working through the same booking details three or four times (having a drop box to select a number of bookings would be great!).
