Recently USPS reworked their priority rates to make it clearer how long a given rate will take in transit. This can be confusing for customers, especially if the products you sell don't ship straight away. This snippet removes the “1-Day”, “2-Day” etc from the rate names. For details on the changes USPS made, see their website.

Paste the following code right before the closing </head> tag of your checkout template:

<script type="text/javascript" charset="utf-8" >
jQuery(document).ready(function() {
	jQuery(document).ajaxComplete(function(event, request, settings) {
		if (settings.url.indexOf('GetShippingCost') != -1) {
			jQuery(".fc_shipping_service").each(function() {
				var reg = /\d-day/i;
				var service = jQuery(this).html();
				if (reg.test(service)) {
					jQuery(this).html(service.replace(reg, "").trim());
				}
			})
		}
	});
});
</script>
