Overview

Amazon Auto Checkout is a Python automation tool that watches an Amazon product page (or wishlist) and completes a purchase when:

• the item is in stock
• the price is at or below your configured maximum
• your Amazon account can sign in successfully

It uses Selenium with undetected-chromedriver to drive Chrome, rotate user agents, and navigate Amazon's checkout flow with minimal manual intervention.

Example use case: automatically buying a high-demand item (e.g. a PS5) the moment it becomes available within your budget.

How It Works

flowchart TD
    A[Start Chrome via undetected-chromedriver] --> B[Open product / wishlist URL]
    B --> C{In stock & price OK?}
    C -->|No| D[Wait & refresh]
    D --> C
    C -->|Yes| E[Sign in to Amazon]
    E --> F[Add to cart]
    F --> G[Proceed to checkout]
    G --> H[Place order]
    H --> I[Done]

Loading

1. Launches an undetected Chrome session.
2. Polls the target URL until stock and price conditions are satisfied.
3. Signs in with your Amazon credentials.
4. Adds the item to cart and completes checkout using your account defaults.

Usage

py main.py

The script runs until it successfully places an order or you stop it with Ctrl+C.

Before You Run

Please review these common edge cases:

• Two-factor authentication (2FA) — the bot may fail to sign in if 2FA is enabled. Disabling 2FA reduces account security and is not recommended.
• Empty cart — start with an empty Amazon shopping cart to avoid accidental multi-item orders.
• Default payment & address — checkout uses your account's saved shipping address and payment method. Verify both are correct before running.
• Regional storefronts — selectors and page layout can differ between Amazon locales; test with your target domain.
• Terms of service — automated purchasing may violate Amazon's terms. Use at your own risk.
