No college experience is complete without textbooks, but they're also so expensive. Chegg has a suite of apps that are helpful to college students, but the one that will save you the most money is Chegg Books. Search textbooks by title or ISBN, and find them at discounted rates! You can also rent textbooks to save a significant amount of money (up to 90 percent!). When you're done with your rentals, simply mail them back with the prepaid shipping label provided.
