After digging through a few eBay listings that wouldn't accept PAPDY20, the cheapest I could get this on eBay was around $214. House comes to around this price but adding 5.6% cashrewards is a much better deal!
Cashback was $11 upon checking out (excl GST I guess): $204.99 after cashback
I'm still salty I got refunded on the 7 piece for $160
