Introduction

Pricing Service is a Python Flask web application that allows you track items of online stores and be notified by email if the item has dropped below a user set minimum price.

This web application was done as a capstone project for the Udemy course, Complete Python Web Course: Build 8 Python Web Apps.

Features

• Scrapes e-commerce websites, including:
  • John Lewis
  • Ikea
  • Nike
  • EB Games
• User can create/edit their profile.
• User may view available stores that they wish to track the items of.
• User may track a desired item from an available store by creating an Alert.
  • Alerts have a minimum price for their corresponding item.
  • If an alert's item drops below its minimum price, the user is notified by email.
  • Alert on user's alert list will indicate if an item has dropped below its minimum price with a visible message.
  • User may edit Alerts.
• Administrators may add new stores to the stores list.
• Extensive documentation website built with Sphinx.
