Javascript snippit to hide/censor price tags on a website. (Note: seems to break interaction with the site, use at own risk)

price_censor.js

(function(context) {
    var priceCensor = "X.XX";
    var pattern=/(\$)(\d([\d\,\.]+)?)/g,
        callback=function(_,dollar,price) {
            price=price.replace(/,/g,''); 
            return dollar + price;
        },
        html = context.innerHTML.replace(pattern,callback);
    context.innerHTML = html;
})(document.body);
