Been a while since this one has been at this price - especially with the new RRP of $199 (bloody lego!) - a good way to get the powered up packs for other builds or convert your hogwarts train or lego city tram.
I was waiting for Amazon to price match but they seem way too slow. Seem to be lots of stock in Vic at least. $7.90 postage if you need it sent.
Can recommend adding the https://www.lego.com/en-au/product/light-88005 light set for this at a later point.
