I just placed a $120 order from Amazon. I almost went to BN for part of the order, but once I knew there was free shipping on orders over $99, I bought all my items from Amazon. So, it did make a difference in my case. I also checked out our local bookstore to compare prices, and hardback books were on average $8 per book more expensive in the bookstore than at Amazon. That's significant! How do these brick and mortar retailers hope to stay in business once people realize the savings they can achieve by shopping online - and no sales tax!! I buy all my airline tickets online. And as a matter of fact, after three long, stressful weeks of car-dealer shopping, I just bought a brand new car online via carsdirect.com. I'm a believer!!
