Once again, the company reaped the benefits of its expansion from bookseller to fully-fledged online retailer. Non-book sales surged 55% to $1.47bn with top sellers drawn from a diverse range of products, including Apple iPods, Similac baby milk, the Sims II video game and Sony Ericsson mobile phones. Despite the result, the shares fell 8% in after-hours trading because of the company's already-rich valuation and its more cautious outlook for next year.
