I went into WooCommerce and found the module: shortcode-cart.php

In this module I found the line

echo '<p><a class="button" href="'.get_permalink(get_option('woocommerce_shop_page_id')).'">'.__('&larr; Return To Shop', 'woothemes').'</a></p>';

and replaced it with:

echo '<p><a class="button" href="http://kiik.com.au/wp/?page_id=609">'.__('&larr; Return To Shop', 'woothemes').'</a></p>';
