Remove Estimate shipping and taxes block in Magento

Hello Friends

To remove the Estimate shipping and taxes block you have to follow step

In order to do this you can copy app/design/frontend/base/default/layout/checkout.xml
 into
app/design/frontend/default/grayscale/layout/ (you need to replace default/grayscale with the path to your theme files)
 and after that
 customizeapp/design/frontend/default/grayscale/layout/checkout.xml removing the following line there:

<block type="checkout/cart_shipping" name="checkout.cart.shipping" as="shipping" template="checkout/cart/shipping.phtml"/>

Another, more correct way (as it will not override whole default layout, so will be more upgrade-friendly) would be to edit local.xml file in app/design/frontend/default/grayscale/layout/ and add the following content right above the closing </layout> at the bottom:

<checkout_cart_index>
        <reference name="content">
                <block name="checkout.cart">
                        <remove name="checkout.cart.shipping"/>
                </block>
            </reference>

</checkout_cart_index>

After that you need to refresh Layouts cache at System > Cache Management.
