Lady Gaga has designed a wristband to show support for Japan. Each wristband is only $5 (shipping, for me, was around $4) and all proceeds go directly to Japan relief efforts. In addition, you can also donate additionally when you buy. She has raised over a quarter million dollars in 48 hours.[link]
Bungie has also made a wristband in turquoise! Same price ($5, with cheaper shipping $1.50) and all proceeds go to Red Cross.
