eBay and half.com

I'd like to talk about another advancement in technology that has helped during my educational process and that's both eBay and the eBay powered half.com Both of these two websites have been extremely beneficial to me during my education because they have provided me with affordable learning materials. While a walk-on at Northern Iowa, I didn't always have the ability to get my books for class right away because of expenses and whatnot. I found that by using these websites, I could not only find affordable books, but I could get books that had previously seen the courses and I could see the notes other students had taken/written in them as well as what they focused on while studying. I know that when eBay was launched, that was not the intent of the site, but it sure has been a nice development. I know plenty of people who may not have had books for class were it not for more affordable options such as these two sites or amazon.com
