It seems to be a special price on ebay for a few days. TRU has a $12.49 delivery charge bringring to $111.48, RRP $149.99. Great for Christmas gift or collection.
Also saw it on TRU Website for $109.99, believe you can buy it with this price in store (If you have purchased the Ultimate Kids Cards from Woolworth or Coles previously, will give you extra 10% off)
It's a great Lego model. It's not perfect but it's bigger than you think. The details are great. Personally I didn't bother about the stickers that wrap around the window pieces.
Highly recommended.
