This is a node script that uses selenium-webdriver to purchase yourself a single, $0.50 Amazon gift card.
Once you clone this repo, you will need to run npm install.
Also, you will need to set up two environment variables. One is AMAZON_USERNAME which is the email address of your Amazon account and the other is... you guessed it... AMAZON_PASSWORD.
Once you have done that, simply use node to run buy_card.js and away it goes.
