Usage

Running the Application

1. Open Command Prompt in the project directory
2. Run the application:

python main.py

Or simply double-click run.bat

Using the Application

First Time Setup (Takes 30 seconds)

1. Enter Your Email: The email address where you want to receive price alerts
2. Click "Save": Your email is saved
3. Click "Test Email" (optional): Verify everything works
4. Done! ✅ Ready to start tracking

Adding Products to Track

1. Product URL: Paste the full Amazon or Flipkart product link

   • Example: https://www.amazon.in/dp/B0XXXXXXXXX
   • Example: https://www.flipkart.com/p/XXXXXXXXX

2. Price Limit: Enter the price (in ₹) at which you want to be notified

   • Example: If a laptop costs ₹50,000 and you enter 45,000, you'll get an alert when it drops to ₹45,000 or below

3. Click "Add Product": The product will be added to the tracking list

Tracking Products

• Start Tracking: Click to begin automatic price checking every 30 minutes
• Stop Tracking: Stop the automatic checking
• Refresh Now: Manually check prices immediately
• Delete Selected: Remove a product from tracking

Activity Log

The log at the bottom shows:

• When products are added/deleted
• When prices are updated
• When emails are sent
• Any errors that occur

Database

The application uses SQLite for data storage:

• tracked_products.db - Contains all product data and price history
• Automatically created in the project directory on first run

How It Works

1. Price Checking: Scrapes the product page to get current price
2. Comparison: Compares with your set price limit
3. Alert Logic:
   • If price ≤ limit → sends email (once per product)
   • If price > limit later → resets, ready to alert again if price drops
4. Scheduling: Checks every 30 minutes automatically

Troubleshooting

Email Not Sending?

1. Check your App Password: Make sure you're using the 16-character App Password, not your Gmail password
2. Verify 2-FA is enabled: Gmail requires 2-Step Verification
3. Click "Test Email": This will show you exactly what the error is
4. Check internet connection: Ensure you have a stable connection

Price Not Updating?

1. The URL might be incorrect or product might be unavailable
2. Sometimes websites block automated scraping - try a manual refresh
3. URL format must be correct - copy directly from the browser address bar

Application Won't Start?

1. Make sure Python 3.7+ is installed
2. Install requirements: pip install -r requirements.txt
3. Check if port is available
4. Run as Administrator if permission denied

Important Notes

⚠️ Email Settings:

• Email credentials are pre-configured in the app
• You only need to enter your recipient email to receive alerts
• Email is sent automatically when prices match your limits

⚠️ Tracking Interval:

• Default is 30 minutes
• Don't set too frequently to avoid blocking by websites
• 30 minutes is a good balance

⚠️ Website Changes:

• If Amazon or Flipkart changes their website structure, the price scraping might not work
• If this happens, try again later or restart the app
