Amazon.com Inc.’s determination to offer shoppers the best deals is prompting merchants selling products on its marketplace to raise their prices on competing websites, a testament to the company’s growing influence over the e-commerce market.
Amazon constantly scans rivals’ prices to see if they’re lower. When it discovers a product is cheaper on, say, Walmart.com, Amazon alerts the company selling the item and then makes the product harder to find and buy on its own marketplace -- effectively penalizing the merchant. In many cases, the merchant opts to raise the price on the rival site rather than risk losing sales on Amazon.
Pricing alerts reviewed by Bloomberg show Amazon doesn’t explicitly tell sellers to raise prices on other sites, and the goal may be to push them to lower their prices on Amazon. But in interviews, merchants say they’re so hemmed in by rising costs levied by Amazon and reliant on sales on its marketplace, that they’re more likely to raise their prices elsewhere.
Antitrust experts say the Amazon policy is likely to attract scrutiny from Congress and the Federal Trade Commission, which recently took over jurisdiction of the Seattle-based company. So far, criticism of Amazon’s market power has centered on whether it mines merchants’ sales data to launch competing products and then uses its dominance to make the original product harder to find on its marketplace. Harming consumers by prompting merchants to raise prices on other sites more neatly fits the traditional definition of antitrust behavior in the U.S.
“Monopolization charges are always about business conduct that causes harm in a market,” said Jennifer Rie, an analyst at Bloomberg Intelligence who specializes in antitrust litigation. “It could end up being considered illegal conduct because people who prefer to shop on Walmart end up having to pay a higher price.”
In an emailed statement, an Amazon spokesperson said: “Sellers have full control of their own prices both on and off Amazon, and we help them maximize their sales in our store by providing them insights on how to be the featured offer.” Walmart declined to comment.
Online merchants typically sell their products on multiple websites, including Amazon, Walmart Inc. and EBay Inc. But many generate most of their revenue on Amazon, which now accounts for almost 40% of online sales in the U.S., according to EMarketer.
Merchants have long complained that Amazon wields outsize influence over their businesses. Besides paying higher fees, many now have to buy advertising to stand out on the increasingly cluttered site. Some report giving Amazon 40% or more of each transaction, up from 20% a few years ago.
Some merchants are keen to increase their sales on Walmart, where it costs less to do business since advertising costs less than it does on Amazon. But sellers say the price alerts are forcing them to maintain allegiance to Amazon and making it harder to diversify their businesses. Walmart routinely fields requests from merchants to raise prices on its marketplace because they worry a lower price on Walmart will jeopardize their sales on Amazon, says a Walmart manager, who requested anonymity to speak freely about an internal matter.
Amazon began sending the price alerts in 2017, and merchants say they have increased in frequency amid an intensifying price war between Amazon and Walmart. Merchants receive the alerts via a web platform they use to manage their Amazon businesses. The alerts show the product, the price on Amazon and the price found elsewhere on the web. They don’t name the competing site with a lower price; the merchants must find that themselves.
