The Digital Book World E-Book Best-Seller list tracks e-book sales ranking and price data across six major e-book retailers with the goal of providing the most accurate picture of which e-books are most often purchased by consumers and at what price point. The full methodology is available here.

Readers who waited until December to load up on the year’s hottest books were wise to do so.

Buy the new John Grisham (Penguin Random House) for $3.29 or Donna Tartt’s sensation “The Goldfinch” (Hachette) for $1.79. Buy “Gone Girl” (Penguin Random House) for $3.29 or all five “Game of Thrones” (Penguin Random House) books for $9.99 (a lot of pages for just 10 dollars).

Many of these titles have been deeply discounted, even from last week. “The Goldfinch”, for instance, was $7.99 on the last Digital Book World Ebook Bestseller List.

As a result, the average price of a bestselling ebook this week is $5.27, a new all-time low. The previous low was in early September: $5.41.

Authors, publishers and agents are still being paid the same amount for each copy of the book by the retailers, meaning that many of these books are being sold at a loss, the aim likely to accrue market share.

While publishers with discounted books are likely moving many copies and shoveling in revenue, they may also be disconcerted with the new perceived value of their wares. Consider a decade ago, for readers to acquire the latest hits from big-name authors within months of their release, they would likely have had to pay $20 to $40 for a hardcover copy.
