thanks, i managed to work it out.. now waiting for trademe to allow me to relist..  hoping im not doing a 5 day wait thing..

Thanks guys..  Seller didnt seem to keen to pay courier back to them.. So trademe came to the party and paid it.. Kudos to trademe.. Great job..  Much appreciated.  A bit frustrating though as it would have been nice if the seller had come to the party.  It was their mistake. Should have been their problem to sort. 

thank you very much for the advise..     Is that a general trademe rule?  are you able to point me to it? a link?  would be good to be able to send the link to the seller.. Appreciate the help
