Why???

We built this in response to the severe tech scalping situation that's happening right now. Almost every tech product that's coming out right now is being instantly brought out by scalping groups and then resold at at insane prices. $699 GPUs are being listed for $1700 on eBay, and these scalpers are buying 40 cards while normal consumers can't get a single one. Preorders for the PS5 are being resold for nearly $1000. Our take on this is that if we release a bot that anyone can use, for free, then the number of items that scalpers can buy goes down and normal consumers can buy items for MSRP.

If everyone is botting, then no one is botting.

Got a question?

Read through this document and the cheat sheet linked in the next sections. See the FAQs if that does not answer your questions.

Installation

Easy_XII has created a great cheat sheet for getting started, please follow this guide. Note: that we do not control the contents of this document, so use some common sense when configuring the bot. Do not ask us why the bot does not purchase an $8.49 item when the minimum purchase price is set to $10 in the configuration file that YOU are supposed to update

This project uses Pipenv to manage dependencies. Hop in my Discord if you have ideas, need help or just want to tell us about how you got your new toys.

To get started you'll first need to clone this repository. If you are unfamiliar with Git, follow the guide on how to do that on our Wiki. You can use the "Download Zip" button on the GitHub repository's homepage but this makes receieving updates more difficult. If you can get setup with the GitHub Desktop app, updating to the latest version of the bot takes 1 click.

!!! YOU WILL NEED TO USE THE 3.8 BRANCH OF PYTHON, 3.9.0 BREAKS DEPENDENCIES !!!

pip install pipenv
pipenv shell 
pipenv install

NOTE: YOU SHOULD RUN pipenv shell and pipenv install ANY TIME YOU UPDATE, IN CASE THE DEPENDENCIES HAVE CHANGED!

Configuration

Make a copy of amazon_config.template_json and rename to amazon_config.json. Edit it according to the ASINs you are interested in purchasing. What's an ASIN?

  • asin_groups indicates the number of ASIN groups you want to use.
  • asin_list_x list of ASINs for products you want to purchase. You must locate these (see Discord or lookup the ASIN on product pages).
    • The first time an item from list "x" is in stock and under its associated reserve, it will purchase it.
    • If the purchase is successful, the bot will not buy anything else from list "x".
    • Use sequential numbers for x, starting from 1. x can be any integer from 1 to 18,446,744,073,709,551,616
  • reserve_min_x set a minimum limit to consider for purchasing an item. If a seller has a listing for a 700 dollar item a 1 dollar, it's likely fake.
  • reserve_max_x is the most amount you want to spend for a single item (i.e., ASIN) in asin_list_x. Does not include tax. If --checkshipping flag is active, this includes shipping listed on offer page.
  • amazon_website amazon domain you want to use. smile subdomain appears to work better, if available in your country.

Examples

One unique product with one ASIN (e.g., Segway Ninebot S and GoKart Drift Kit Bundle) :

{
	"asin_groups": 1,
	"asin_list_1": ["B07K7NLDGT"],
	"reserve_min_1": 450,
	"reserve_max_1": 500,
	"amazon_website": "smile.amazon.com"
}

One general product with multiple ASINS (e.g 16 GB USB drive 2 pack)

{
	"asin_groups": 1,
	"asin_list_1": ["B07JH53M4T", "B085M1SQ9S", "B00E9W1ULS"],
	"reserve_min_1": 15,
	"reserve_max_1": 20,
	"amazon_website": "smile.amazon.com"
}

Two general products with multiple ASINS and different price points (e.g. 16 GB USB drive 2 pack and a statue of The Thinker)

{
	"asin_groups": 2,
	"asin_list_1": ["B07JH53M4T", "B085M1SQ9S", "B00E9W1ULS"],
	"reserve_min_1": 15,
	"reserve_max_1": 20,
	"asin_list_2": ["B006HPI2A2", "B00N54S1WW"],
	"reserve_min_2": 50,
	"reserve_max_2": 75,
	"amazon_website": "smile.amazon.com"
}

If you wanted to watch another product, you'd add a third list (e.g. asin_list_3) and associated min/max pricing and increase the asin_groups to 3. Add as many lists as are needed, keeping in mind that the main distinction between lists is the min/max price boundaries. Once any ASIN is purchased from an ASIN list, that list is remove from the hunt until FairGame is restarted.

Start Up

Previously your username and password were entered into the config file, this is no longer the case. On first launch the bot will prompt you for your credentials. You will then be asked for a password to encrypt them. Once done, your encrypted credentials will be stored in amazon_credentials.json. If you ever forget your encryption password, just delete this file and the next launch of the bot will recreate it. An example of this will look like the following:

python app.py amazon
INFO Initializing Apprise handler
INFO Initializing other notification handlers
INFO Enabled Handlers: ['Audio']
INFO No credential file found, let's make one
Amazon login ID: <your email address>
Amazon Password: <your amazon password>
INFO Create a password for the credential file
Credential file password: <a password used to encrypt your amazon credentials>
Verify credential file password: <the same password that was entered above>
INFO Credentials safely stored.

Starting the bot when you have created an encrypted file:

python app.py amazon --test
INFO Initializing Apprise handler
INFO Initializing other notification handlers
INFO Enabled Handlers: ['Audio']
Reading credentials from: amazon_credentials.json
Credential file password: <enter the previously created password>

Example usage:

python app.py amazon --test

Best Buy

Best Buy is currently deprecated because we don't yet have an effective way to determine item availability without scraping and processing the product pages individually. Future updates may see this functionality return, but the current code isn't reliable for high demand items and checkout automation has become increasingly hard due to anti-bot measures taken by Best Buy.

Original code still exists, but provides very little utility. A 3rd party stock notification service would probably serve as a better solution at Best Buy.

This is fairly basic right now. Just login to the best buy website in your default browser and then run the command as follows:

python app.py bestbuy --sku [SKU]

Example:

python app.py bestbuy --sku 6429440

Notifications

Sounds

Local sounds are provided as a means to give you audible cues to what is happening. The notification sound plays for notable events (e.g., start up, product found for purchase) during the scans. An alarm notification will play when user interaction is necessary. This is typically when all automated options have been exhausted. Lastly, a purchase notification sound will play if the bot if successful. These local sounds can be disabled via the command-line and tested along with other notification methods

Apprise

Notifications are now handled by Apprise. Apprise lets you send notifications to a large number of supported notification services. Check https://github.com/caronc/apprise/wiki for a detailed list.

To enable Apprise notifications, make a copy of apprise.conf_template in the config directory and name it apprise.conf. Then add apprise formatted urls for your desired notification services as simple text entries in the config file. Any recognized notification services will be reported on app start.

Apprise Example Config:

# Hash Tags denote comment lines and blank lines are allowed
# Discord (https://github.com/caronc/apprise/wiki/Notify_discord)

https://discordapp.com/api/webhooks/{WebhookID}/{WebhookToken}

# Telegram
tgram://{bot_token}/{chat_id}/


# Slack (https://github.com/caronc/apprise/wiki/Notify_slack)
https://hooks.slack.com/services/{tokenA}/{tokenB}/{tokenC}

Pavlok

To enable shock notifications to your Pavlok Shockwatch, store the url from the pavlok app in the pavlok_config.json file, you can copy the template from pavlok_config.template_json.

WARNING: This feature does not currently support adjusting the intensity, it will always be max (255).

{
  "base_url": "url goes here"
}

Testing notifications

Once you have setup your apprise_config.json you can test it by running python app.py test-notifications from within your pipenv shell. This will send a test notification to all configured notification services.

Troubleshooting

Re-read this documentation. Verify your JSON.

I suggest joining the #tech-support channel in Discord for help from the community if these common fixes don't help.

Error: selenium.common.exceptions.WebDriverException: Message: unknown error: cannot find Chrome binary The issue is that chrome is not installed in the expected location. See Selenium Wiki and the section on overriding the Chrome binary location .

The easy fix for this is to add an option where selenium is used (`selenium_utils.py``)

chrome_options.binary_location="C:\Users\%USERNAME%\AppData\Local\Google\Chrome\Application\chrome.exe"

Error: selenium.common.exceptions.SessionNotCreatedException: Message: session not created: This version of ChromeDriver only supports Chrome version 87

You are not running the proper version of Chrome this requires. As of this update, the current version is Chrome 87. Check your version by going to chrome://version/ in your browser. We are going to be targeting the current stable build of chrome. If you are behind, please update, if you are on a beta or canary branch, you'll have to build your own version of chromedriver-py.

Raspberry-Pi-Setup

Maybe this works?

  1. Prereqs and Setup
sudo apt update

git clone https://github.com/Hari-Nagarajan/fairgame
cd fairgame/
pip3 install pipenv
export PATH=$PATH:/home/<YOURUSERNAME>/.local/bin
pipenv shell 
pipenv install

  1. Leave this Terminal window open.

  2. Open the following file in a text editor:

/home/<YOURUSERNAME>/.local/share/virtualenvs/fairgame-<RANDOMCHARS>/lib/python3.7/site-packages/selenium/webdriver/common/service.py

  1. Edit line 38 from self.path = executable to self.path = "chromedriver", then save and close the file.

  2. Back in Terminal...

python app.py
  1. Follow Usage to configure the bot as needed.

Frequently Asked Questions

1. Can I run multiple instances of the bot?

Yes. For example you can run one instance to check stock on Best Buy and a separate instance to check stock on Amazon. Bear in mind that if you do this you may end up with multiple purchases going through at the same time.

2. Does Fairgame automatically bypass CAPTCHA's on the store sites?

  • For Amazon, yes. The bot will try and auto-solve CAPTCHA's during the checkout process.
