Add to Archive Pages

I was wondering if there was an easy way to add to the Archive \ Shop pages?

I can get it to display but not carry the cost through to the basket\checkout.

add_action( ‘woocommerce_after_shop_loop_item_title’, array( $this, ‘gift_option_html’ ), 10 );

Many thanks for a great addon.
