To compare prices across Instacart, Walmart, and Amazon Fresh, we collected data on 30 common grocery items across five categories: produce, dairy, pantry staples, snacks, and meat.

Prices were gathered in August 2025 from three major cities—New York, NY; Los Angeles, CA; and Chicago, IL—to account for regional variations. Scrape Grocery Platforms for Real-Time Price Tracking to ensure the data was current and accurate, sourced directly from each platform’s website or app.
The data collection process involved:
To ensure consistency, prices were normalized for differences in package sizes and brands. Delivery and service fees were included in total cost calculations, and membership benefits (e.g., Instacart Express, Walmart+, Amazon Prime) were considered. The analysis also incorporated consumer feedback and market share data from recent studies to provide context on service quality and platform popularity.

In Los Angeles, Walmart maintained the lowest prices, while Amazon Fresh was competitive for packaged goods. Chicago showed similar trends, with Walmart leading in affordability and Instacart consistently higher due to store-specific pricing. These findings highlight the importance of localized pricing strategies in the grocery market.
Price is not the only factor influencing consumer choice. Each platform offers unique features:
For budget-conscious shoppers, Walmart is the most cost-effective option due to its low prices and minimal fees for pickup. Amazon Fresh offers strong value for Prime members, particularly for those prioritizing convenience and speed. Instacart, while more expensive, provides unmatched store selection, making it suitable for consumers seeking specific brands or specialty items.
