Let's see all the things you can get out of this:
1. $25 - can buy you an NBATV subscription, snacks, porn subscription to a website, 3 grams of weed and more..
2. Adding to your knowledge - hey, this never hurts...if you go on jeapordy, whose to say that they won't talk about the Columbian exchange?
3. Helping another human being - a shooin for heaven!
Man, if I had free time I'd jump all over this deal.
