Online Grocery Prices Drop: Key Insights

  • Record Drop in Prices: August saw a 3.7% decrease in U.S. online grocery prices, offering consumers some relief from the ongoing pressures of inflation.

  • Growth in Online Shopping: Online grocery shopping surged in 2023, with major platforms like Instacart and Walmart leading the trend, despite price drops in categories such as groceries and computers.

  • Looking Ahead: The future of online grocery is poised for continued growth, driven by convenience and tech advancements, but ongoing challenges like inflation and supply chain disruptions will keep price volatility in play.


According to Adobe’s Digital Price Index, online grocery prices in the United States fell by 3.7% in August. This marks the largest month-over-month decline since Adobe began tracking the data in 2014. 

The drop offers a rare moment of relief for consumers who have been grappling with the effects of inflation on grocery bills in recent years. 

Rising Popularity of Online Grocery 

Online grocery shopping, which made up almost 10% of the total U.S. grocery market in 2023, has grown in popularity, with platforms like Instacart and Walmart seeing increased demand. Nearly half of all digital grocery sales come from in-person pickups, but home delivery services have surged due to ongoing promotional efforts. 

Online Price Trends in Key Categories 

Using artificial intelligence and machine learning, the Adobe Digital Price Index (DPI) tracks online prices using the Fisher Price Index and real purchase quantities from two adjacent months. 

Let’s look at their data to see which online product categories in the U.S. have increased and decreased in price, compared to the previous month and year:

Online Price Change in the United States by Product Category, 2023-2024

  • As of August 2024, only the online product categories of nonprescription drugs, medical equipment, personal care, and groceries have increased in price compared to August 2023.

  • While jewelry was the category with the largest month-over-month (MoM) price increase at 2.31%, grocery (3.7%, the largest MoM decline since Adobe began tracking online prices in 2014) and computers (-4.58%) saw significant declines. 

Grocery prices have risen over 20% since 2019, but inflation has eased in 2024, with annual price increases slowing to around 1%. Despite this, prices are not expected to return to pre-pandemic levels, and the current dip in online grocery costs may be temporary.
