Bought my first Timbuk2 bag or rather pouch in Singapore at Orchard Cineleisure and it is the Timbuk2 Shagg Bag 2012. It cost S$35. It it an accessory pouch that can be attached to the straps of your Timbuk2 bag.
In my case, I am attaching it to my Timbuk2 Q Backpack 2011. You can store iPhone, earphone, keys or even coins in that pouch which can be access easily since it is in front.
According to the sales person, this shop is the official Timbuk2 shop in Singapore. The owners in San Francisco do come down once a year to take a look.
