Monster Energy Offers Tracker

This project consists of three components: a data collection system, a website, and an email notification service. Together, they track and display Monster Energy drink promotions across Austrian supermarkets.

Key Features

1. Data Collection

Website Structure:

• Homepage: Displays current offers
• Notifications Page: User registration/deregistration and preference management for email alerts
• Legal Pages: Privacy policy (/datenschutz) and imprint (/impressum)
• Fully responsive design (mobile and desktop compatible)

3. Email Notification Service

• Sends automated alerts when new offers are detected
• Allows users to manage subscription preferences via email or website
