Shitty script I built to help me purchase a Ryzen 9 5950X on Amazon.
Of course, you can use it to buy anything, and now it has support for Newegg and Walmart as well.
Looks like I'll eventually end up adding even more integrations thanks to the paper launch and cancelled orders due to lack of stock.
None of this shit is tested that well really, and I haven't quite touched Python for 2 decades, so you're on your own if things go south.
Keep in mind that it ignores currency, so set your prices and item links carefully.
Since I work with PowerShell, the scripts and these instructions are based on that, but of course you could use any shell you want in order to run this.
There's a bunch of issues around break handling. And still more refactor to do around multiple buyer implementations.
One note up front: However many items you want to purchase, you'll need that many accounts on each platform you're going to enable.
This step is necessary only on the first run.
PS D:\CODE\FuckThisPaperLaunch> cp .\.env.sample .\.env
Then edit the .env file to update these values:
NUMBER_OF_ITEMS (How many items you're trying to buy.)
ENABLED_BUYERS This is a comma separated list of buyers we want running. Currently valid values are: AmazonBuyer, NeweggBuyer and WalmartBuyer
We default to Amazon and Newegg only. If you want to try WalmartBuyer as well, you'll probably need to raise the WALMART_STOCK_CHECK_MIN_WAIT_IN_SECONDS setting to some crazy high value just for a glimmer of hope of avoiding the aggressive captcha challenges.
NeweggBuyer is currently being worked on as well, but I feel uneasy about that particular integration since Newegg keeps asking for the fucking CVV2 code.
ITEM_NAME_1 (Just for logging purposes.)
MAX_BUY_COUNT_1
MAX_COST_PER_ITEM_1 (This is total cost per item, including taxes and shipping. Beware: Currency is ignored.)
AMAZON_LOGIN_EMAIL_1 (As stated above, you should use separate accounts for each item you're trying to buy.)
AMAZON_LOGIN_PASSWORD_1
Feel free to change the AMAZON_ITEM_ENDPOINT_1 setting as well according to what you're actually trying to buy. There are some example endpoints in the environment file.
If you have more items to buy, keep editing and/or adding new entries for each of these configuration values that are suffixed with 2, 3, etc.
With the addition of NeweggBuyer and WalmartBuyer implementations, their respective configurations have been added as well, so if want to either of them, you'll need to update the settings that are prefixed with NEWEGG_ or WALMART_.
Apparently Newegg can also require you to confirm your credit card number in some cases, so we have a NEWEGG_CARD_NUMBER_1 setting to set it up. However, I would just stop the bot and go over that confirmation manually once instead of typing my credit card number in the environment setting of a random script I found on GitHub, built by a random guy on the Internet.
Not that setting the CVV2 number should make you any less wary, but unfortunately that's a requirement due to the Newegg purchase flow.
Meaning, if you indend to enable NeweggBuyer, you'll have to provide the NEWEGG_CVV2_1 value as well.
Update the IS_TEST_RUN value to False when you're happy with the settings. The script will not actually buy anything as long as this is set to True.
Modify the chromedriver-py version in requirements.txt to match your Chrome version.
You should stick to the latest version that has the same major version with your browser.
ie. If your Chrome version is 87.0.4280.141, you should use 87.0.4280.88 of chromedriver-py since that is the latest driver of the 87.x.x.x series available. You should not use 88.0.4324.27 since it won't be able to connect to Chrome 87.
Available versions can be seen here.
This step is necessary only on the first run.
Open up a PowerShell prompt. (Windows Terminal, ConEmu, or just a PS prompt)
Then run the init.ps1 script.
PS D:\CODE\FuckThisPaperLaunch> .\init.ps1
This will basically initialize a virtual environment, activate it, and install dependencies.
On the same PowerShell prompt just run the start.ps1 script.
PS D:\CODE\FuckThisPaperLaunch> .\start.ps1
This will simply run the script. Of course you could just use PyCharm Community Edition or Visual Studio to run this if you wanna fiddle around with the code and debug it.
In order to stop the bot, just press CRTL+C and wait for it to shut itself down, disposing the browser connections. It will take some time, but I suspect it might be safer to wait for it to do its thing. Since I'm not really familiar with the native driver, I'm not really sure whether it leaks or not otherwise.
Note: If you run into captcha verifications on Walmart, just open a new tab in the same browser, go past the captcha challenge, and close that tab. The bot should be able to pick up from there on the original tab.
If, however, you keep getting capthca challenges down the line, it's not worth it. Just disable WalmartBuyer instead.
If you run into login verification on Newegg, you'll need to enter your OTP manually, and then the bot will pick up from there. You can raise the NEWEGG_LOGIN_CONFIRMATION_WAIT_IN_SECONDS value if you need more time to receive and open the Newegg email.
