Though I don't tend to go for such things, I recently jumped on the bandwagon and donned a green wristband to draw attention to the genocide in the Darfur region of Sudan. These wristbands aren't as widely distributed as Lance Armstrong's LIVESTRONG wristbands or the ONE wristbands so I had to order them myself.
Well, long story short, they only come in bags of 10 or more. Though several people in my office have already claimed some of the extras, I still have four left. If you would like me to send you one (no cost - but a donation to one of the organizations working in Darfur would be nice), just e-mail me and if you are one of the first four to respond, I will pop one in the mail to you.
