Amazon Wishlist Pricewatch











Periodically check your public Amazon wishlist for price reductions.
This package will send you a notification (SMTP email and/or telegram) each time a product on your publicly available wishlist reaches a new lowest price. Price still not low enough? You'll only receive another notification for the same product when the price drops further.
Pip install the package, fill in the configuration file and schedule to run with your preferred task scheduler. E.g. Windows Task Scheduler / launchd (Mac OS) / cron (Mac OS / Unix).
Uses the wonderful requests and BeautifulSoup4. No need for the overhead of a headless browser as all data can be gathered from the plain html.

How It Works
Once installed and configured, each run of pricewatch downloads and stores your wishlist as JSON and does price comparisons against items seen in previous runs. When a new lowest price for a product is seen you receive a notification, and the new price is saved to JSON for future runs.
Schedule the script to run as often as you like with Task Scheduler/launchd/cron, and you're good to go.
Getting Started
Prerequisites
Python >=3.8
Installation
Install with pip (recommended):
pip install amazon-wishlist-pricewatch
pricewatch

Or clone the git repo:
git clone https://github.com/sam0jones0/amazon_wishlist_pricewatch.git
cd amazon_wishlist_pricewatch
pip install -r requirements.txt
cd ./amazon_wishlist_pricewatch
python3 ./pricewatch.py

(Optional) If you want telegram notifications:
pip install python-telegram-bot

Set Configuration
Fill in the config file located at amazon_wishlist_pricewatch/config.json
If you can't find it enter pricewatch (or python3 ./pricewatch.py if you cloned the repo) into your console. Location of the file will be printed.
Detailed config file documentation here.
Test Notifications
In config.json Set send_test_notification to "1" and run pricewatch. A test notification(s) should be sent and pricewatch will exit. Remember to set back to "0" once you're done.
Set Running Schedule
You can use any task scheduler you like to run pricewatch / pricewatch.py Here's a few suggestions.
Windows
I recommend using "Windows Task Scheduler". You can use the GUI or for e.g. to create a task that runs once each time the system boots enter the following into an elevated (Run as Administrator) cmd.exe/Powershell.
schtasks /create /tn "Amazon Wishlist Pricewatch" /tr "C:\Path\To\Your\Python\exe\python.exe D:\Path\To\amazon-wishlist-pricewatch\amazon_wishlist_pricewatch\pricewatch.py" /sc onstart /RU WindowsUserName /RP WindowsPassword

More examples and guidance on setting different schedules here
Mac OS
You can use cron, launchd, automator or any other tool. For e.g. to use launchd to create a task that runs once each time the system boots create
the following file ~/Library/LaunchAgents/local.amazonwishlistpricewatch.pricewatch.plist and paste in:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>Label</key>
<string>local.amazonwishlistpricewatch.pricewatch.plist</string>
<key>ProgramArguments</key>
<array>
<string>/usr/local/bin/python3</string>
<string>/path/to/amazon_wishlist_pricewatch/pricewatch.py</string>
</array>
<key>RunAtLoad</key>
<true/>
</dict>
</plist>

More information on launchd here
Unix/Linux
I assume you'll be fine! Perhaps use cron.

Notification Mode

"1" for email.
"2" for Telegram.
"12" for email and Telegram.

Send Test Notification
Set to "1" to have the script attempt to send a notification to each method specified and then exit. Change back to "0" to have the script run normally.
Using Gmail
If you have 2FA enabled you can create an app password and put that in sending_email_pass.
Not recommended, but you can use your usual Google account password if you enable "Less secure app access". I'd recommend creating a new Gmail account if you do this.
Using Telegram

Download / install Telegram.
Create a bot with Telegram's BotFather bot and keep a note of the token.
Create a new group where you will receive notifications and add your new bot to it.
Send at least one message to the group.
Visit https://api.telegram.org/botXXX:YYYYY/getUpdates replacing XXX:YYYYY with your token from step 2 and take a note of the chat id.
Add your chat id and token to config.json.

User Agent
You don't need to change this, but you can. Enter "my user agent" into Google to see your browser's user agent.
