Half.com codes for current customers are pretty rare, so this one took me by surprise. Code EARLYBIRD15 is good for $15 off a $50 purchase. It does not appear to be a one-time use code, so it’s worth a try if you’re in the market for textbooks. I used the code to purchase the textbook for my college Biology and paid about half of what the used textbook sells for in the school bookstore.
