# Setup
## Install Dependencies
```
PUPPETEER_PRODUCT=firefox npm install puppeteer
```
## Setup Configuration
1. `cp config.example.json config.json`
2. Edit `config.json`:
* `username`: newegg username
* `password`: newegg password
* `cv2`: code on the back of your credit card
* `item_page`: the part of the URL (starting with a slash) for the product after `https://www.newegg.ca` (eg: `/amd-ryzen-9-5900x/p/N82E16819113664`)
* `refresh_time`: amount of time between page refreshes (with a random variance)
* `refresh_tries`: the number of times the script will check before quitting (to avoid getting banned)
* `auto_submit`: set this to false if you want to do a test run (everything up to the actual purchase)
* `price_limit`: set this to a number you don't want your cart total to exceed before checking out
