Donate to the Troops for Free!

Click on the 'Support the Troops' link and there is a place to have HBO send stuff to the troops. They want your information, so be prepared for that, but it looks like a good cause.

I had my sound off when I went there so I don't know if it's got a loud intro, just be prepared if you're at work or something.
