More than 90 million consumers shop on Amazon.com, and that number is steadily increasing. So, no matter how big or small or what they sell, third-party sellers can expand their base by showing their wares on Amazon.

Steve Weber, a former newspaper reporter and now an online book dealer, has penned a book designed to show readers how to profit by partnering with this popular and highest-rated online retailer.

In fact, as Weber explains, Amazon makes it easy for want-to-be merchants to set up shop from home with little or no up-front investment, risk or advertising.

Sounds great, doesn't it? But that doesn't mean you won't have to work or invest in time and application. Weber explains in easy-to-understand language how to get started, manage inventory, meet legal requirements and handle other aspects of doing business with Amazon.

As he did in his previous books on selling used books, selling on eBay and marketing books and business online, Weber provides solid, pragmatic information to help even the greenest of amateurs leverage the Amazon brand name to advantage.

In addition to his own tried-and-tested experience in dealing through Amazon, Weber has solicited the perspective of others who have expanded their product sales by linking with the merchandiser.

Since Amazon doesn't charge sellers any fees until their goods are sold, this may be the perfect opportunity for many to supplement their income in these trying financial times.
