Beating Amazon

| Comments

Everytime I see a site that requires user interaction, it gives me a chance to practice some hackery. Case in point: Amazon black friday deals.

Amazon wants you to wait on the page counting down like you have nothing better to do. As a programmer I’d rather make a script to do that for me.

It brought me back a bit as their version of jQuery is 1.6.4. Anyway here’s the script, you can open the javascript console with Ctrl + Shift + J then paste the code below in or you can use the bookmarklet:

bookmarklet: Amazon Clicker 

(function($) {
    function re__waitForIt__serve($item) {
        var interval = setInterval(function() {
            var $buyButton = $item.find('.btn');
            if ($buyButton.length) {
                clearInterval(interval);
                $buyButton[0].click();
                setTimeout(function() {
                    alert('Item (hopefully) available to buy!');
                    $item.css('outline', '1px solid green');
                }, 5000)
            }
        }, 100);
    }
    jQuery('body').delegate('li[id]', 'mouseenter.grabber', function() {
        var $this = $(this);
        $this.css('outline', '1px solid red');
        $this.delegate('*', 'click.grabber', function() {
            re__waitForIt__serve($this);
            $this.css('outline', '1px solid blue');
            $('*').unbind('.grabber')
            alert('All set to buy item');
            return false;
        });
        $this.bind('mouseleave.grabber', function() { $this.css('outline', 'none'); });
    });
})(jQuery);

(Tested in Chrome)

Think there’s a better way to do this? Did you ever have to do something like this?
