I cannot change the USPS shipping wording

Hi.

We use USPS to ship. However, we do not want to identify the specific shipping method (Priority Mail, Express Mail, etc), and instead we just want to specify Standard Shipping or Expedited Shipping.

I have edited the language file in includes/languages/english/modules/shipping/usps.php to:

define('MODULE_SHIPPING_USPS_TEXT_OPT_PM', 'Standard Shipping');
define('MODULE_SHIPPING_USPS_TEXT_OPT_EX', 'Expedite Delivery');

However, when I try to do a test order, in the estimate shipping window, it still says Priority or Express.

Also, how do I remove the number of days delivery. I want to override and set to definite delivery dates.

Please advice.

Thanks

You can test it with the code in RED:

echo $title . ' - ' . $type. '<br>';
if ($type == 'PARCEL') {
  $title = 'FRED';
}
// add $this->usps_countries to title to test actual country

and then adapt it as needed ...
