Nintendo Switch Console 2019 - Neon Blue/Red $448 ($405 via 10% off Gift Cards) + Delivery (Free with Club Catch) @ Catch

A bit of a workaround but may be worth the hassle for some.

Neon Blue/Red console $448 or purchase $450 worth of gift cards for $405 (effectively will cost $403.20 with a little leftover on the gift card).

10% off Physical Catch Gift Cards (Delivered or In-Store) @ Australia Post (thanks doweyy)

Cashback is 1% at Shopback and Cashrewards which brings the console down to sub $400.

To sweeten the deal, you can now start earning flybuys points on your purchase. Your first linked transaction gets you 10x points as a regular user, or otherwise 20x points as a Club Catch user.

• 10x points on the purchase as a regular user = 4480 points ($22.40 flybuys dollars)
• 20x points on the purchase as a Club Catch user = 9960 points ($44.80 flybuys dollars)

Could be worth signing up to Club Catch for the points too as the first month is free (which you can cancel before it rolls over to your second). If you've been a member in the past, paying the extra $6.50 for a month's membership would give you an extra $22.40 worth of flybuys dollars in the form of points 😉

*Edit: Few more options via referral and Zip could knock off up to $30 if you're willing to go the distance. See here (Thanks WhatWouldBiggieDo)
