This book by Marsh Collier is as about as good as it gets. It is easy to understand. Though the book was written a few years ago, all of the information is still relevant. A few of the tools, etc. that are listed and described are revised on eBay's site, but the changes are rather minor and her how-to lessons are perfect. I highly suggest anyone wanting to buy and/or sell on eBay purchase this book. A++
