My little bit for Haiti: a donation for each book

I've been trying to figure out what I can do, and here's what I came up with:

For the next week, anyone who orders my book I'll donate my share of the proceeds ($4), and match it with my own donation, to the Red Cross for Haiti. That's just $8 per book, but it's something.
I'll see if I can round up other authors to do the same.

The only way I know to do this is through my big indie bookstore in Denver, Tattered Cover. 
Follow these instructions, and they will let me know how many get ordered, and I'll make the donation accordingly. I'll also sign the copy for you and write a personalized inscription if you like.


INSTRUCTIONS:

Call or email the Colfax Avenue Tattered Cover: 303-322-7727 books@tatteredcover.com and say:

1. You want an autographed/inscribed copy of COLUMBINE, by Dave Cullen
2.Their computer listing for the book will indicate to them that I'll come in to sign the books, and has contact info for them to reach me. (Don't even mention the Haiti thing. I'll take care of that.)
3. What you want in the inscription (including your name or who you want it to).
4. Your name, phone number, address and credit card info.

Tattered Cover Bookstore will handle sales, shipping, etc. I will sign and handle the donations.
