I have used many different websites to buy books online: Amazon.com, eBay, Barnes and Noble, bestbookbuys.com, alibris.com. Tonight, I used a different site for the first time: half.com. I bought all of my textbooks for the next semester and one for the following semester for easily half of what I expected to pay. Plus I got them without visiting three dozen dorm rooms and standing in line for forty-five minutes. And the books were cheaper than I could have gotten from any other internet site.

So, though I still recommend using Amazon.com to gather information about a book and using bestbookbuys.com to check the main outlets for the cheapest price, I now recommend using half.com to make the actual purchase.
