You can get BXGY-like exposure without paying fees if your book sales are strong, relative to other titles in your category. Amazon pairs your book with a related title in a display nearly identical to BXGY's # Best Value #, but in this case it's called #Better Together#.
To see this in action, go to any book's detail page on Amazon. Under the heading #Better Together#, you'll see the book paired with another book, much like BXGY, albeit without the extra 5 percent discount.
If your book is the best-selling title in its niche, your book can appear on the Better-Together spot for several other related titles--another example of how strong sales on Amazon create more exposure for you.
