I came from a regular family without father, when I still went to college, I was not able to buy a new textbook. So, every semester I hunted for secondhand textbooks. At that time, I had to go to work everyday 7am - 4pm and college from 5pm - 9pm. I was so happy when I managed to finish my study.
I would like you to know, that I found this site where you can sell college textbooks you don't need anymore, but where you can also rent and buy textbooks for college and high school. Feel free to click to the link to find more details about this opportunity.
