I make it no secret that I'm a huge fan of Timbuk2 bags, packs, purses, whatever. If they started producing frankfurters, I'd probably like those too. I like Timbuk2 because I believe they make a great product that is actually worth its retail price. When there's a sale on any of their stuff... and especially when there's a sale on ALL of their stuff, you can count on me to broadcast it.
Amazon is specific in the terms of this 25% off Timbuk2 Promo that it is only for a limited time and that they will simply put an end to it when they desire. If there's some Timbuk2 kit that you fancy over there, I'd not wait too long before biting.
