Avanti Modular Wine Rack FROM $3 delivered @ Jack's Wine! (Normally $29.99)
This item is actually free if you sign up to their newsletter - you just have to pay the postage charges. I tried a few postcodes and it seems to be $3 in Sydney and in Perth... so that might be a flat rate for the whole country (if you see otherwise, please let us know)
It looks quite good for $3 shipped!!
