I'd jump in the bandwagon and suggest that you order online as well.
Just got myself 20 rolls of XP2 from freestyle not too long ago. Seems like a steal even with the shipping when compared to the price i'd otherwise pay here in OZ (i'm all for stimulating our own economy but NOT when i can get the item for half the price)
Otherwise, try this ebay seller called 'film festival' based in thailand. More expensive than US but still cheaper than OZ even after the shipping cost - cheaper shipping since its from Asia.
HAve a look at 'cheap shots au' on ebay as well. Local seller and prices seems cheaper from what the shops
If you ready to buy bulk, B & H photo or Freestyle etc is the way to go methinks.
If you are only looking for a few rolls, i'd consider 'film festival'
