# PriceAdjustPro - Full Documentation for LLMs

## Overview
PriceAdjustPro is a specialized SaaS platform designed for Costco shoppers to maximize their savings through automated price adjustment tracking. Costco auto-connect, unlimited receipt uploads, automatic 30-day price-drop detection and spend analytics are free for everyone, permanently. Price-adjustment alerts and the searchable Sale Directory are normally a paid tier, and are free for every member through December 31, 2026; pricing after that will be announced before the free period ends.

## How It Works
1. **Upload**: Users upload digital or physical (photo) Costco receipts.
2. **Parse**: The system uses Google Gemini AI to extract line items, prices, item numbers, and transaction dates.
3. **Monitor**: The system compares these items against official Costco promotions and warehouse markdowns.
4. **Alert**: If a price drop is detected within 30 days of purchase, the user receives an alert.
5. **Claim**: Users take the alert (with the item number) to the Costco Returns desk to receive their refund.
