The summary template gives a shopping cart-like summary of an order. Unlike the main shopping cart in the cart.php template file, the summary does not have cart management controls. Like the cart.php template file, the summary.php template primarily uses Cart Tags.
It is used on the checkout page (checkout.php template file) and the order confirmation page (confirm.php template file) by calling the shopp() tag:
<?php shopp('checkout','cart-summary'); ?>
