    var expires = new Date((new Date()).valueOf() + fifteenDays);
    document.cookie = "visited=true;expires=" + expires.toUTCString();
}

var str = '13.3999996185303px';
str.replace( 'px', '' ); // Output will be 13.3999996185303
// or
parseFloat( str ) // Output will be 13.3999996185303

this.addEventListener("load", loadTimer, true); 
function loadTimer(e) {
    count = $(".MagicScrollItem").children().length;
    var total_width = count*265;
    jQuery('.MagicScrollItem').parent().addClass('scroll-wrapper'); 
    jQuery('.scroll-wrapper').css({width: total_width+"px"});

var custom_timeout_function = ( function () {
      var timers = {};

        if (!uniqueId) {
              uniqueId = "Don't call this twice without a uniqueId";
        }
        if (timers[uniqueId]) {
              clearTimeout (timers[uniqueId]);
        }
        timers[uniqueId] = setTimeout(callback, ms);
      };
})(); 
custom_timeout_function( function(){  
    jQuery( '.woocommerce-tabs ul.tabs li a' ).each( function(){
