Free textbooks
If you have been to college, or you’re currently in college, you know that it is expensive to buy your textbooks. In some cases, it can cost hundreds of dollars for a textbook that you will use for nine weeks, sometimes longer.
This is why most textbook makers enable you to test the books out during a free trial period, which lets you figure out if you want to buy them or not. This person suggests taking a screenshot of the textbooks, although this sounds more cumbersome than purchasing the books yourself. It could be worth it to avoid the headache.
