Expansion has propelled Amazon.com in innumerable directions. While the website still offers millions of books, movies, games, and music, electronics and other general merchandise categories, including apparel and accessories, auto parts, home furnishings, health and beauty aids, toys, and groceries ring up more than 50% of sales. Shoppers can also download e-books, games, MP3s, and films to their computers or handheld devices, including Amazon's own portable e-reader, the Kindle. Amazon also offers products and services, such as self-publishing, online advertising, e-commerce platform, hosting, and a co-branded credit card.
