Used Math Textbooks

Where can I sell used college textbooks in the Philippines?

Can you recommend a site or a buyback store wherein I can sell used textbooks effectively? But i only intend to sell those within here in the Philippines.

1. Ebay and Craigslist would be the basics as would amazon
2. De La Salle University - Buy Back Books drive. 1. Go to De La Salle University. 2. Enter the campus, but think of any excuse that will make the guard let you enter (do not use Admissions because that won't buy). If you are an Alumni, you can enter at all times. 3. Look for "Buy Back Books" stall and sell your books there. 4. Get the cash and splurge! Or if you can't or won't do those things, then just head for Recto Avenue corner Quezon Boulevard and sell your books there - you'll just get a couple of bucks (as they'll buy it for a very low price).
