ShowCart after AddToCart

This module renames the ’Add to Cart’ button to ’Buy Now’. When you click on this button, the product gets into the cart (of course just then if the product doesn’t has obligatory fields) and the content of the cart appears on a new page.
There are two types of this module. The first replace the 'Add to Cart' button. The second add another button called 'Buy Now' which will redirect to cart.

The extension can be found here: http://www.opencart.com/index.php?route ... n_id=13714
