Haven't seen this set being sold in any other retailers (including Amazon AU), though idrk what to feel about this, at almost half price RRP thought it may be useful for some.
Some other decent prices, for example Bugatti Bolide Technic @ $45. Had been ATL @ $39 last year though.
If you manage to find something else to hit $150 min spend, can stack with:
CBA Yello cashback offer, min spend varies, check your specific offer.
AMEX cashback offer
Have a blessed day
Kind of a sad looking set for the money. Get the world globe instead and at least you have a nice display set that can also be added on top of to map out past and future travels
