I managed to gain 2,000 FlyBuys pts + week 2 of 4 ($120/week) for 10,000 FlyBuys pts, and used 5% discounted gift card for extra 5% OFF. In total, saved heaps with special priced products + discount + points.
Enjoy saving(s) guys :)

The only good deal here is the $20 off $160 spend.
The selection of products for the $10 off $40 spend offer is very limited and those are often discounted more than 25% without having to buy $40 worth at once.
The $10 off $150 spend makes no sense. If you end up paying the same in the end you may as well take the extra $10 worth of free goods.
150 - 10 = $140
160 - 20 = $140
