Query: Gwendolyn Hilliard's textbook experience

I needed books for summer school. I tried Amazon.com because I had heard so much about it from other students. At first I was a little leary because it was a company I had no experience with. But I took a chance and was surprisingly happy. I ordered the books around May 7th or so and they were due on June 2nd. They arrived within the same week of ordering them. Of course I was pleasantly surprised that they were so quick. I can say that I had a very good experience with Amazon.com and I hope to do more business with this company. Gwendolyn Hilliard
