Scraping Grocery Prices

Scraping Grocery Prices from Blinkit, Instacart, and BigBasket for Competitive Analysis

Published on September 30, 2025

In a rapidly digitized retail world, the grocery sector has transformed into a highly dynamic battlefield. From hyperlocal delivery models to large-scale fulfillment centers, pricing strategies vary drastically across platforms like Blinkit (India), Instacart (USA), and BigBasket (India). For businesses operating in the grocery or fast-moving consumer goods (FMCG) domain, staying ahead of pricing trends is critical to ensure competitive parity, profitability, and customer retention.

This blog explores how businesses can use web scraping to collect grocery pricing data from Blinkit, Instacart, and BigBasket. It further explains how to use this data for competitive pricing analysis, including technical techniques, real-world applications, and ethical considerations.

Scraping Grocery Prices

1. Why Grocery Price Scraping Matters

📉 Price Drives Purchase Decisions
Most grocery shoppers are price-sensitive. A ₹2–₹10 difference in staples like milk, rice, or oil can drive significant customer churn.

🏷️ Dynamic Pricing is the Norm
Prices change due to:

  • Demand spikes
  • Regional availability
  • Promotions & coupons
  • Supply chain delays
Scraping gives real-time visibility into those price fluctuations.

🛒 Omnichannel Behavior
Customers compare prices between platforms (Blinkit, BigBasket, Instacart) before placing an order. Businesses need the same lens for pricing intelligence.

3. Scraping Blinkit for Grocery Prices

🌐 About Blinkit
Blinkit (formerly Grofers) is a 10-minute grocery delivery app serving major Indian cities.

⚙️ Scraping Strategy
Blinkit content is dynamically rendered and location-specific. Use:

  • Selenium or Playwright for JS-rendered pages
  • BeautifulSoup for parsing

Sample Code to Scrape Product Data:

from selenium import webdriver
    from bs4 import BeautifulSoup
    import pandas as pd
    import time

    driver = webdriver.Chrome()
    driver.get("https://www.blinkit.com/s/atta")

    time.sleep(5)
    soup = BeautifulSoup(driver.page_source, 'html.parser')

    products = []
    for item in soup.find_all('div', class_='ProductCard'):
        try:
            name = item.find('p', class_='name').text
            price = item.find('span', class_='new-price').text
            size = item.find('span', class_='qty').text
            products.append({'Product': name, 'Price': price, 'Size': size})
        except:
            continue

    df = pd.DataFrame(products)
    df.to_csv('blinkit_prices.csv', index=False)
    driver.quit()

📍 Pin Code Based Filtering
Blinkit requires pin code detection. Use automation or their internal API with pin-based GET requests to fetch hyperlocal data.

4. Scraping Instacart Grocery Prices

🌐 About Instacart
Instacart partners with multiple U.S. grocery chains like Costco, Safeway, Kroger, and provides local pricing and delivery services.

⚙️ Scraping Strategy
Instacart heavily uses JavaScript and geo-targeting:

  • Use Selenium + headless browser
  • Pass location-specific parameters (ZIP codes)
  • Parse category and product JSON endpoints

What to Target:

  • Product name
  • Store (e.g., Costco, Publix)
  • Club or non-member price
  • Discounted offers
  • Product weight

Caution:
Instacart’s legal terms explicitly restrict scraping. Ensure compliance by using:

  • Low frequency
  • Ethical use (not resale)
  • Data anonymization for internal BI

5. Scraping BigBasket Grocery Prices

🌐 About BigBasket
BigBasket is India’s largest online supermarket, offering wide inventory, region-specific pricing, and subscription services.

⚙️ Scraping Strategy:

  • BigBasket uses public product URLs
  • You can use Requests + BeautifulSoup
  • Or inspect network calls for paginated JSON endpoints

Sample URL:
https://www.bigbasket.com/pc/fruits-vegetables/fresh-vegetables/

Sample Code:

import requests
    from bs4 import BeautifulSoup

    url = "https://www.bigbasket.com/pc/fruits-vegetables/fresh-vegetables/"
    headers = {"User-Agent": "Mozilla/5.0"}

    r = requests.get(url, headers=headers)
    soup = BeautifulSoup(r.content, 'html.parser')

    items = []
    for card in soup.find_all('div', class_='item-details'):
        name = card.find('h3').text.strip()
        price = card.find('span', class_='discnt-price').text
        items.append({'Product': name, 'Price': price})

    import pandas as pd
    df = pd.DataFrame(items)
    df.to_csv('bigbasket_prices.csv', index=False)

6. How to Use the Data for Competitive Analysis

Once you’ve collected the pricing data, here’s how to turn it into insights:

📊 6.1 Build a Price Comparison Dashboard
Visualize:

  • Price per item across platforms
  • Discount differences
  • Out-of-stock comparisons
Use tools like:
  • Excel / Google Sheets
  • Power BI / Tableau
  • Python (Matplotlib / Seaborn)

📍 6.2 Regional Pricing Strategy

  • Map price differences by pin code or ZIP code
  • Detect regional pricing gaps
  • Launch zone-specific discounts or ad campaigns

🧠 6.3 ML Model: Predict Pricing Trends
Feed your scraped historical data into a model to predict:

  • When a product is likely to go on discount
  • Category-level price volatility

🛒 6.4 Inventory and Supply Chain Optimization

  • Detect which products go out of stock quickly on rival platforms
  • Use these insights to maintain your stock buffer

7. Business Use Cases

Business Type Scraping Benefit
Retailers Match or beat competitors’ pricing dynamically
FMCG Brands Track how their products are priced across resellers
Dark Stores Monitor competitor stockouts and pricing to adjust fulfillment
E-commerce Aggregators Standardize price data across cities and platforms
Market Analysts Forecast seasonal pricing and inflation impact

8. Challenges and Solutions

Challenge Fix
JavaScript-loaded content Use Selenium or Playwright
IP bans Use rotating proxies
Inconsistent naming Use product ID or barcode where possible
Frequent DOM changes Use try-except + update scraping rules regularly

9. Ethical and Legal Considerations

Always follow scraping best practices:

  • Respect each site’s robots.txt
  • Use data for internal competitive analysis, not for resale
  • Avoid scraping customer data
  • Set user-agents, throttle requests, avoid DDOS-type loads
⚠️ Instacart and BigBasket may have anti-scraping clauses in their terms. Use APIs where officially available, or explore partnerships for data-sharing.

  • Real-time competitive positioning
  • Better promotional planning
