Tracking Daily Price Drops from Amazon & Walmart USA Using AI

In today’s e-commerce battleground, pricing is no longer static — it’s dynamic, competitive, and often algorithmically optimized by giants like Amazon and Walmart. For brands, sellers, and price-conscious consumers, staying ahead of these rapid-fire changes is both a challenge and an opportunity. This is where AI-powered price tracking comes in.

In this blog, we explore how Product Data Scrape enables businesses to track daily price drops from Amazon and Walmart USA using intelligent scraping, machine learning, and Web Scraping Amazon E-Commerce Product Data — offering a significant edge in strategy, margin optimization, and market positioning.

Why Price Drop Monitoring Matters

Retailers change product prices multiple times per day, especially on platforms like Amazon and Walmart. According to industry estimates:

• Amazon updates prices up to 2.5 million times daily
• Walmart’s algorithm reacts to competitor pricing in real time
• Flash sales and limited-time deals are often unannounced
• Without automated tracking, businesses miss out on:
• Timely insights into competitor behavior
• Opportunities for real-time repricing
• Detecting underpriced inventory for reselling
• Avoiding overstocking on declining-value SKUs

That’s why it’s crucial to Extract Walmart E-Commerce Product Data alongside Amazon pricing to capture these rapid changes and stay competitive in real time.

What Is AI-Based Price Tracking?

AI-based price tracking combines web scraping with machine learning models to analyze price fluctuations across large datasets. Unlike manual tools or simple scrapers, AI-based systems can:

• Detect anomalies (e.g., extreme price drops)
• Identify price drop patterns and sale timing
• Track brand vs private label pricing
• Predict the probability of future discounts

Product Data Scrape provides an AI-driven platform that extracts and analyzes millions of data points from Amazon.com and Walmart.com every day. Our Custom eCommerce Dataset Scraping service ensures clients receive tailored, high-accuracy data feeds aligned with their pricing intelligence and competitive monitoring needs.

Sample Dataset – Daily Price Drops

Tide Pods 96-Count	Walmart	$24.99	$19.97	20%	12:45 PM EST	Yes

LEGO Creator 3-in-1 Set	Walmart	$29.99	$23.88	20%	01:15 PM EST	No

This kind of time-stamped price data allows businesses to capitalize on opportunities and respond instantly. Combined with a comprehensive Walmart Product and Review Dataset , it empowers brands to not only track price changes but also correlate them with customer sentiment and product performance — enabling smarter retail decisions.

How AI Helps Detect and Learn Price Behavior

Machine learning adds deeper layers of intelligence:

• Price Trend Modeling: Predict whether a drop is part of a short-term sale or long-term markdown
• Category-Level Analysis: Compare price behavior across categories like electronics, toys, and groceries
• Retailer Behavior Insight: Understand when and how often Walmart reacts to Amazon’s prices (or vice versa)

This lets Product Data Scrape deliver not just the price, but also the reason and the forecast behind the change.

Why Focus on Amazon & Walmart USA?

Together, Amazon and Walmart dominate the U.S. retail landscape:

• Amazon.com: 2.5 Billion+ monthly U.S. visitors, 350M+ total products
• Walmart.com: 500 Million+ monthly U.S. visitors, 50M+ total products

Platform	Monthly Visitors (U.S.)	Total Products
Amazon.com	2.5 Billion+	350M+
Walmart.com	500 Million+	50M+

Why monitor both?

• Amazon changes prices dynamically using internal pricing AI
• Walmart reacts competitively based on Amazon’s prices
• Both offer exclusive discounts and loyalty pricing (e.g., Prime deals, Walmart+)

Tracking both platforms gives a 360° view of U.S. retail pricing. Using tools like the Web Scraping API for Walmart , businesses can automate the collection of real-time pricing, availability, and promotional data — ensuring they don’t miss critical shifts in market behavior.
