Great board game for a great price - $24.95
Will need to combine with another item to hit the $49 spend for free shipping.
Splendor - $34.42 is probably a good one (https://www.amazon.com.au/Asmodee-SPL01-Splendor/dp/B00IZEUF...)
The Crew The Quest for Planet Nine Strategy Game - $26.88 (https://www.amazon.com.au/Crew-Quest-Planet-Nine-Strategy/dp...)
I think the deal ends in like 20 minutes though - so get in quick!
