Bungie Studio's T-Shirt drive to raise funds for the relief effort is going very well; they've almost raised $93, 000 US.
If you haven't yet, especially if you're a Halo fan, go buy one of these shirts. It's for a great cause and the $15.00 US Bungie donates to the American Red Cross can literally save a life or lives.
UPDATE: Bungie has commented even further in tonight's Weekly Update. To date, they've made $120, 450.00 in donations to the American Red Cross from their "Fight the Flood" t-shirt.
