At Outdoor Retailer, Timbuk2 ran a promotion to either trade in your old bag or donate $40 in exchange for a special edition Timbuk2 RED bag. Timbuk2 has been donating 5% of the sales of these messenger bags to the Global Fund to help fight AIDS in Africa. I donated my $40 and am now the proud owner of a Timbuk2 RED Optic Messenger bag.
