you should look for places that you can sell to/from within NZ or NZ and AUS. I'm pretty sure that ebay has an australian wing, if nothing else. and I'm sure there are used book shops in NZ just like there are everywhere else, so... you can try that as a last resort. :)

i love Borders too. I like the mood so much better than that of Barnes and Noble. It's warmer in Borders, cozier, and the snacks tend to be better... :)
