If you are able to buy downloadable textbooks, you will then have the option to read college textbooks online now and any time that is convenient. Some professors will have downloadable articles available which won't need to be purchased. This is a real money saver.
This is a great option if it is available. Many students are carrying their laptops and Ipads with them to class today. If you are lucky enough to have a professor who thinks of allowing you to download college textbooks online this will save you a considerable amount of money.
