Metropolitan Opera Rush Ticket Sniper

Readme.md

###What it is

The Met Sniper script is a simple way to get access to rush tickets from the Metropolitan Opera. It is a script you install, which will run on the rush tickets page, constantly reloading until it sees that tickets are available, and navigate you to the page where you can claim them.

This should give you enough time to complete the purchase flow.

###How it works

Simple, it uses a plugin that modifies injects scripts you desire into pages - a so called userscript - then looks for the "buy" button and clicks it when it finds it.

###How to install

It's only tested on the chrome web browser, but any browser + plugin capable of running "userscripts" should work. Below are instructions for the chrome web browser:

• install tampermonkey: https://chrome.google.com/webstore/detail/tampermonkey/dhdgffkkebhmkfjojejmpbldmpobfkfo?hl=en
• click on the icon that appears to the right of your nav bar and go to the "dashboard"
• install the userscript by clicking the button with a plus on it in the upper right hand corner and pasting in the code in "metsniper.js"
• navigate to metopera.org and create an account.
• log in to your account
• navigate to the rush tickets page.
• As long as you are logged in and on the rush tickets page, the page should be reloading itself constantly.
• Tickets are released at noon, so check back as soon after noon as you can, I don't know how long tickets are held.
• To disable the script, either close your tab or click on the tampermonkey icon and click "Enabled" to disable it.
