I went to the Saratoga Library book sale and love it when I find some goodies for cheap. I purchased an old "Casper" and an old "Dennis the Menace" comic for only 25c each. Cool!
BTW, if you think 25c is cheap, then here's a better deal. Go to your local comic book store on May 3, 2008, and it will be the annual Free Comic Book Day. Yes, they're free!! I'm working at Lee's Comics in Mountain View that day, so if you are a San Francisco Bay Area local, stop by and say hi.
