Was on Chapel street for breakfast and saw Macpac have extra 20% off clearance items. Ended up buying a Genesis Aztec 85L for $231.9 - which is a pretty good price, given it's top of the range nylon waterproof backpack with lifetime warranty. I prefer Macpac over Kathmandu packs - but it's a matter of taste.
How it works is you get 50% off (overpriced) RRP $579.95, which brings it down to $289.95, and now another 20% - down to $231.95. Genesis 85L was extremely good value at $187.95 but went for Nylon for durability/waterproof. Have a look at the link for more offers. Offers are available online and in-store.

Went to Kathmandu and they had Interloper for $250, which is not a bad deal either (listed at $230 online):
