A study conducted by e-commerce specialist Profitero claims that Amazon remains the low price online grocery leader by a slim margin over Walmart. Profitero’s “Price Wars: Grocery, Household & Beauty” report found that Walmart.com’s grocery prices average 1.8% more than Amazon’s.

Target ranked third in the study with Walmart’s Jet.com coming in fourth.
“With consumer buying decisions increasingly based on price, and dynamic pricing made possible through technology and advanced algorithms, the so-called ‘price wars’ have escalated,” according to Profitero. “Some recent industry studies have fundamentally concluded that while Amazon is often less expensive than its online counterparts, its price-leading position is being challenged by competing retailers, especially Walmart.”
