Amazon on fire with Fire.

SAN FRANCISCO — A couple of years after it launched its website in 1995, Ama­zon was the subject of an unflattering report entitled Amazon.Toast. The pundit who penned it predicted that the fledgling online bookseller would soon be crushed by Barnes & Noble , a book-retailing behe­moth that had just launched its own site.

Far from being crushed, Amazon is doing the crushing. Borders , a once­ mighty book chain, was flattened this year. B&N looks like a frightened capybara running from a fierce Brazilian she-war­rior. Amazon is now one of the web’s most successful e-tailers. Even Apple is feeling the heat.

On Sept. 28, Jeff Bezos, Amazon’s boss, unveiled a tablet computer called the Kindle Fire. It will compete with gadgets such as B&N’s Nook Color tablet and Apple’s iPad. The new Amazon tablet, which has a somewhat smaller screen than the iPad and only offers Wi-Fi con­nectivity, is likely to be just the first salvo in a titanic battle.

Like Apple, Amazon boasts a huge collection of online content, including e-books, films and music. And like Apple, it lets people store their content in a com­puting “cloud” and retrieve it from almost anywhere. But the two firms part com­pany when it comes to pricing. The Kindle Fire, which will be available from mid-November in America, will cost only $199. That is far less than the cheapest iPad, a Wi-Fi-only device that costs $499.

B&N responded to the Kindle Fire by cut­ting the price of its Nook Color to $224.

Last week, Amazon also rolled out a new range of Kindle e-readers, the cheapest of which costs just $79.

“We are building premium products and offering them at non-premium prices,” beamed Bezos.

Amazon’s decision to undercut its rivals is partly a tactic designed to disrupt the tablet market, which is still dominated by the iPad. Gartner , a research firm, be­lieves that Apple’s device will account for almost three-quarters of the 64 million tablets it thinks will be sold worldwide this year. Amazon’s pricing strategy also reflects one of the firm’s core beliefs,

which is that cheap stuff makes customers cheerful. Call it the Walmart of the web.

Low prices are not the only thing under­pinning Amazon’s success. The company is technologically adept, and it has a knack of delighting customers with in­novations such as its $79-a-year “Amazon Prime” shopping service in America, which offers members free, two-day ship­ping and other benefits. Such goodies have been crucial to its growth. But its ability to drive down the prices of every­thing from cameras to cloud computing gives it a colossal competitive advantage.

A recent study by William Blair , an investment bank, underlines the price gap between Amazon and its rivals in the retailing world. The report compared the prices of 100 randomly selected goods at each of 24 American retailers with those items that were also available on Ama­zon. com. It found that almost half of the goods were listed on the online retailer’s site too, and that Amazon’s prices for individual products were on average 11 per cent below those of the stores. The study also noted that Amazon’s discounts were in many cases deeper than those offered by the retailers’ own websites.

Admittedly, as an online outfit, Amazon does not pay sales taxes in American states where it has no physical presence.

Many cash-strapped states are now keen to pass laws that would change this — a move Amazon is loudly and unsurprising­ly opposing. But the William Blair study concludes that even if it has to cough up more taxes, Amazon will still be able to offer prices that are lower than those of many rivals.

The firm’s huge scale and its massively popular website, which it will use to pro­mote the Kindle Fire, give it an edge. And it enjoys another advantage too.

“Amazon does not have to worry about the impact of its pricing on a legacy store system,” explains Kirthi Kalyanam, a professor at Santa Clara University’s Retail Management Institute.

Amazon Web Services, or AWS, which rents computing capacity in its giant data centers to customers, has also won a repu­tation for being cheap. Comparing cloud­computing prices is tricky, but observers of the market report that AWS is typically one of the lowest-cost providers.

“Amazon operates with economies of scale that are practically impossible to match,” says Reuven Cohen of Enomaly ,

which runs SpotCloud, an online market­place where firms sell excess cloud-com­puting capacity.

The cloud is crucial to the success of Amazon’s gadget strategy. Most analysts think that the firm loses money on the hardware that it sells. But it hopes that its cheap tablet will be wildly popular and therefore boost sales of Amazon’s cloud­based content, just as the Kindle e-reader boosted sales of e-books. It’s like free parking outside Walmart — you want potential customers to see what’s in the window.

The good news for Amazon is that tab­let users seem more inclined to splash out on stuff than web shoppers who use PCs, according to Forrester , another research firm. One possible explanation for this is that tablet buyers tend to be richer; anoth­er is that the immersive experience tablets create encourages more impulse buying.

Whatever the reason, Amazon will have to hope that its gambit works, because its business model has at least one worrying downside. Its profit margin is a page-thin 3-4 per cent, partly because it has invested so heavily in the cloud. Now it is going head-to-head with Apple, which made a juicy $7.3 billion net profit on revenues of $28.6 billion in the latest quarter. Apple may not want to provoke a price war in the tablet market, where it sees plenty of growth to come.

But if it does return fire, Amazon could get its fingers toasted.
