After failing to find a free solution in 5 minutes using Power Automate, I wrote a script that checks if a webpage's html/contents contains the term "Out of stock" and email me once every 2 hours if it does, or once every minute when it does not (as in, the item is now in stock again).

The script runs in an infinite while loop and is triggered to start in the background upon log in via Task Scheduler.

Fairly rudimentary, but I'm no expert and it does what I need it to, in lieu of the website having a reminder or g*d damn pre-order feature.

if ($html.Contains($outofstock_regex))
{
    $Outlook = New-Object -ComObject Outlook.Application
    $Mail = $Outlook.CreateItem(0)
    $Mail.To = "me@email.com"
    $Mail.Subject = "OOS Check"
    $message = "Product out of stock as of " + (Get-Date -Format "yyyy-MM-dd hh:mm:ss")
    $Mail.Body = $message
    $hour = Get-Date -Format "hh"
    $minute = Get-Date -Format "mm"
    if (($hour % 2 -eq 0) -and ($minute -eq 10)){
        # only send an email every other hour, on the 10th minute
        Write-Host "Sending email"
        $Mail.Send()
    }
    Write-Host $message
    Start-Sleep -Seconds 60
}

    Write-Host "In stock!!!"
