What’s the prize?

The day when I came and bought my first textbook in USA, I recognized that the textbook is extremely expensive than my country. At the moment I just study ESL program, but the prize’s still expensive. I paid almost $100 just for 2 textbook. I have a friend from college and he told me that if you are in college. A book normally costs $150.00 in average. Moreover, some books might even cost more $250. Therefore, you suppose to pay $900 if you take 4 classes a semester. It’s a nightmare for all students, right?
However, there are 2 ways to avoid that nightmare to save some bucks for your future. You can buy used textbook from your friends or someone who already took that class, but make sure about the edit condition from your instructor because each class has different require for the text book. Second, you can buy used/new book from the internet. It’s a good way because you can compare the prizes and determine which one is good for you. Here is some websites that I want to share to you, is gotten from my friend:

Have fun and enjoy, my friends!
