Until this year, there was no major competition for the bookstore. This year there was a place downtown that carried books for most classes. It was a relief to have someone finally break up the monopoly. If students sell books through them, they get to set their own prices and only have to pay a 25-cent service charge. Lastly, a Tech student's cheapest source for books is other students.
Used books are the way to go.
These books are publicized mostly by word of mouth. That reminds me, I've got to make up another one of those posters. If I'm lucky I can pay for next term's books with the proceeds.
