# Project: SAVR

# Project Goal

## Problem & Solution

Many people want to buy products but prefer to wait for a price drop. Money has become an important part of our lives in 2025. However, tracking prices manually across platforms like Amazon, Walmart, and Costco is time-consuming and frustrating. In the fast-paced lifestyle we have now, we need to find solutions that allow people to save their much valued time.

## Common Problems Shoppers Face:

- Price Changes Frequently: Customers miss out on the best deals due to unpredictable discounts.

- Forgetting Saved Items: Many add products to their carts but forget to check back.

- Lack of Notifications: Most platforms don’t alert users when prices drop.

- Overpaying for Products: Shoppers might pay more than necessary without price comparison.

## Our Solution – The Price-Matching App

**To solve this, our app will:**

- Compare prices across multiple retailers and give them the best value.

- Save items users are interested in.

- Notify them when the price drops.

- Help them shop smarter with real-time updates.



This app will simplify online shopping, ensuring users get the best deals without constant price-checking.

#### Delayed Price Updates: Prices may change frequently, affecting accuracy.

Mitigation: Optimize web scraping frequency and use caching techniques.

#### Security Concerns: Handling user authentication securely.
