I used the add to cart message hook in Woocommerce to edit the text and remove some classes from certain buttons. It seems this hook is now deprecated in Woocommerce 2.1 and
This worked for me
add_filter( 'wc_add_to_cart_message', 'custom_add_to_cart_message' );
function custom_add_to_cart_message() {
global $woocommerce;
$return_to = get_permalink(woocommerce_get_page_id('shop'));
$message = sprintf('%s %s', $return_to, __('Continue Shopping', 'woocommerce'), __('Product successfully added to your cart.', 'woocommerce') );
return $message;
}
Edited: Thanks for the correction Kaarel Kaspar
