+## Shopping Lists 🛍️
+
+The price tracker automatically generates daily shopping lists showing the best deals for each store:
+
+### Features
+- **Best Price Selection**: Automatically finds the lowest current price for each product
+- **Store-Specific Lists**: Separate shopping lists for each tracked store
+- **Savings Calculation**: Shows how much you save compared to target prices
+- **Customizable Preferences**: Set minimum savings thresholds, maximum items, and delivery schedules
+- **Multiple Formats**: View online, print, export to CSV, or email daily lists
+
+### Daily Automation
+Set up automatic daily shopping lists:
+
+```bash
+# Generate and send shopping lists manually
+python shopping_list_scheduler.py --force
+
+# Test without sending (dry run)
+python shopping_list_scheduler.py --dry-run
+
+# Set up daily cron job (9 AM daily)
+echo "0 9 * * * cd /path/to/price-tracker && python shopping_list_scheduler.py" | crontab -
+```
+
+### Shopping List Preferences
+
+For each store, you can configure:
+- **Enable/Disable**: Turn shopping lists on/off per store
+- **Minimum Savings**: Only include items with savings above threshold
+- **Maximum Items**: Limit list size to avoid overwhelming
+- **Out of Stock**: Include/exclude unavailable items
+- **Delivery Time**: Schedule when to send daily lists
+- **Notifications**: Email and/or webhook delivery
+
+### Web Interface
+
+Access shopping lists via the web interface:
+- **View All Lists**: See current shopping lists for all stores
+- **Store Details**: Detailed view with full product information
+- **Send Immediately**: Manually trigger email/webhook delivery
+- **Manage Preferences**: Configure settings per store
