Why shipping estimator shows with free shipping item

When a customer has a free shipping item in the cart there is also a shipping estimator still displayed. this has confused some of my customers. why is it displayed and how can i get rid of the estimator for a free shipping item?
Thanks,
Robert

Providing you do not have other shipping modules display when you have a cart that is Free Shipping ...

Using your templates and overrides, you could customize the file:
/includes/templates/your_templates_dir/templates/tpl_shopping_cart_default.php

and add the code in RED:

<?php
[B]if ($shipping_weight == 0) {
  echo '<div>Free Shipping! ' . '<br></div>';
}
[/B]      if (SHOW_SHIPPING_ESTIMATOR_BUTTON == '2'[B] && $shipping_weight > 0[/B]) {

Now the Shipping Estimator will not show when you have set the Shipping Estimator to display on the shopping cart (set to 2) ...

NOTE: if you were trying to hide the button for the Shipping Estimator when set to 1, you would do a similar change to the code higher up in the code where it refers to:

    if (SHOW_SHIPPING_ESTIMATOR_BUTTON == '1') {

Just FYI, if you want to have the "Free Shipping" image on the cart page -- replace in
/includes/templates/your_templates_dir/templates/tpl_shopping_cart_default.php

<?php
      if (SHOW_SHIPPING_ESTIMATOR_BUTTON == '2') {

with

<?php
if ($shipping_weight == 0) {
  echo '<div id="freeShippingIcon"><img src="includes/templates/template_default/images/always-free-shipping.gif" alt="Always Free Shipping" title=" Always Free Shipping " width="94" height="54"></div></div>';
}
      if (SHOW_SHIPPING_ESTIMATOR_BUTTON == '2' && $shipping_weight > 0) {
