I know this will get negged for some reason or another considering how expensive Kathmandu is in the first place.
I personally found this very useful as I'm going back packing for three months.
Also stacked with 7% cashback (was 4.8% expires 23/3)
Some bargains that I found.
Hybrid 70L Backpack Harness Wheeled Luggage Trolley v3 Was $549.98 Now $299.98
Gluon Beyond 18L Backpack v3 Was $99.98 Now $59.98 Add-on for the backpack above
Interloper gridTECH 70L Backpack v2 Was $599.98 Now $379.98
Hopefully this is helpful for someone :)
7% cashrewards hasn't been applied to the prices above
Got one of these last week http://www.kathmandu.com.au/pack-raincover-v2medium.html and it maybe one of the best prices for this item by a brand name. Also available in two other sizes.
