After purchasing a humble book bundle, go to your download page for that bundle. 
Open a console window for the page and paste in the below javascript

this fork downloads all formats and does so without using jquery (since that didnt work for me)

note that if you are in chrome, chrome will not download the pdfs for you by default, to fix this
Settings (chrome://settings) --> Advanced --> Privacy and security --> Content settings --> PDF documents --> Download PDF files instead of automatically opening them in Chrome --> Turn ON
Settings (chrome://settings) --> Advanced --> Downloads --> Ask where to save each file before downloading --> Turn OFF

var pattern = /(MOBI|PRC|\.zip|EPUB|PDF( ?\(H.\))?|CBZ|Download)$/i;
var nodes = document.getElementsByTagName('a');
for (i in nodes) {
    var a = nodes[i];
    if (a && a.text && pattern.test(a.text.trim())) {
        download(a.attributes['href'].value, i);
    }
}
function download(url, i) {
    var iframe = document.createElement('iframe');
    iframe.id = "dl_iframe_" + i;
    iframe.style.display = "none";
    document.getElementsByTagName('body')[0].appendChild(iframe);
    iframe.src = url;
    console.log('iframe set to', url)
}
