Why is it so difficult to buy used textbooks online?

The main issue with used books is that, unless you purchase them at your college bookstore, they are typically sold by students who just finished the course. This means that most used textbooks are sold by individuals, on many different textbook sites, at different prices, and your best bet at finding the lowest price is to use a textbook price comparison. An additional benefit of We Compare Books is that we do not archive our data, this means that every search that we do is done live, and is accurate up to the minute. This may be an issue if the textbook you require is very popular and you are trying to buy it during the beginning of a semester, the prices are likely to change often, and the faster you buy the textbook the more likely you are to get the best price.
