Buying textbooks? It's a great idea to compare book prices online before you buy from local bookstores. I almost fainted when I found out the prizes of books my son needed for this semester. One book costs a little less than a thousand and the others are priced from Php 1200 to 1800. Looking to save on his books, I tried searching online. True enough, the books are a lot cheaper. Plus, I know I got the best prices because I was able to compare the prices from different websites.
