# Amazon Price Watch

Simple script to watch Amazon product prices and send a notification when the price drops below a desired threshold. Useful to watch out for "Warehouse Deals" or used items that are only available for a short time.

Script written in Node.js. Uses the pushover API to send notifications.

Installation

Beside Node.js you need the following modules: Request, Cheerio and Pushover-Notifications.

To install the required dependencies execute:

npm install request cheerio pushover-notifications

Configuration

Configuration is done in config.json:

{
  "pushover": {
    "user": "XXX",
    "token": "XXX"
  },
  "global": {
    "currency": "EUR",
    "urlPrefix": "http://www.amazon.de/gp/offer-listing/",
    "urlSuffix": "/ref=olp_tab_all"
  },
  "products": [
    { "name": "Name of product",
      "productId": "B00CKPCJNO",
      "priceThreshold": "28.00"
    },
    { "name": "Name of product #2",
      "productId": "B000PKFFNW",
      "priceThreshold": "90.00"
    }
  ]
}

Change pushover.user and pushover.token to your Pushover user and application token.

Depending on your locale you need to change global.currency and the Amazon domain in global.urlPrefix.

If you only want to monitor new products change the value of global.urlSuffix to /ref=olp_tab_new?condition=new. To track only used products change it to /ref=olp_tab_used?condition=used.

Usage

Create a crontab entry to execute node app.js once in a while.
