Magento - do not display prices to users not logged in

If we have to hide prices for guest users everywhere.

We just have to follow below steps-

Open app/design/frontend/base/default/template/catalog/product/ folder and copy price.phtml file to the app/design/frontend/theme_package/your_theme/template/catalog/product/ folder and then Place the following code on top of it:

if(!Mage::getSingleton('customer/session')->isLoggedIn()){
echo 'Login to See Price
';
return;
}
