Script designed to track modifications on a specific webpage

Attempting to purchase items online has become a frustrating challenge as stock seems to disappear within minutes of being added :/

I am currently working on creating a custom grease/tampermonkey script to monitor the page and notify me when products become available...

Before delving too deep into development, I'm curious if there are any existing scripts out there with similar functionality (despite my unsuccessful Google search so far)

Additionally, I am unsure if greasemonkey supports running scripts at specific time intervals - this is new territory for me in terms of Javascript/greasemonkey... Any guidance or alternate suggestions would be greatly appreciated

What browser is your go-to choice? I can suggest a couple of firefox extensions that might help with that Check4Change and Update Scanner .

To implement the code, you need to identify the specific elements you are interested in.

    if (document.getElementById('')) {
        alert("alert");
    } else {
        setInterval('location.reload();',15000); //page reload every 15 seconds
    }
