Earlier today, a fellow Bloomfield Hills poster wrote a favorable review for Buy.Com. She indicated that it is a terrific site from which she had bought books. Well, I wanted to offer my two-cents as well, recommending Buy.Com. As people who may have read a lot of my posts are aware, I watch a lot of DVDs, and many of those DVDs are ones that I purchased from Buy.Com. Their prices are indeed better than Amazon's in almost all cases, and shipping is free when your order totals more than $25.00. And probably one of the best things is that, if you use them for a while and then stop using them for a month or two, they will send you special offers to entice you to shop at their site again. For example, I hadn't ordered anything from them for a couple months, and then three weeks ago they sent me an email offering me 10% off of a single order. Really nice prices, when you consider that they are 10% off of Amazon, plus that 10% offer, plus free shipping.
The one negative point I would make about the site is that they don't have an overly-wide selection of older or more unusual titles. But if you are looking for a copy of "Walk the Line" and "Harry Potter" and "Chronicles of Narnia", then Buy.Com is the best I have found.
