Have I mentioned that FedEx is just freaking amazing?
He's diverting Operation Give's resources for the next few weeks to the tsunami victims, and offered Operation Give's Salt Lake City Warehouse, and FedEx has offered both to take a planeload of goods to the Indian Ocean area, but to pick up and transship those donated goods from your house to the warehouse.
Now I wouldn't advocate FedExing flats of water bottles, but here's what they are trying to collect or purchase (hint - you can send them money):
Medical supplies: Bandages, alcohol, disinfectants, etc.
New Cooking utensils
You can sent money to them by Paypal (click here), or you can assemble some of the required NEW ITEMS ONLY, and call them at the number on the linked page, and they will arrange FREE FedEx shipping.
Again, be conscious of what you're shipping; don't spend $50.00 of FedEx's fuel to ship $10.00 worth of items.
But here's another quick-reaction way that you can make a difference on the ground over there.
