Answer 2

Try this:

$("input[name=freight-type]").change(function() { 
    alert( $(this).parent().find(".price:first").text() )
});

closest() goes UP through the DOM tree, so it would starting looking in div.fregith and then go up the DOM tree from there.

try this as your selector:

$(this).next('label').find('.price')
