I'm running the Avenue of the Giants half-marathon with the Leukemia & Lymphoma Society's Team in Training. While regular old donations are always happily accepted, I'm also fundraising by selling books (and soon, DVDs) from my large collection. All proceeds from these sales on my Amazon storefront, less Amazon's commission and shipping fees, go directly to my Team in Training fundraising.
Right now there are around 150 books, mostly in "new" or "used-very good" condition, up for sale. Take a look - you might find something you've been wanting for ages, or that you never thought about before. And it's for a great cause.
I'm adding more titles all the time and will soon start adding DVDs as well.
Thanks and GO TEAM!
