@De Dokta   I have just installed this in a 234bs cart, and things work very well. Thank you!   One thing I would like to see is: Since the customer is buying as a guest, once they move to checking_shipping, is there really a need to offer them the choice of changing addresses in their address book, which they don't have?       If we could have a check in checkout_shipping to see if the customer is a guest, we can eliminate that, and make the guest checkout smoother ...       Here's where it needs to be addressed in checkout_shipping.php <div class="page-header">   <h1><?php echo HEADING_TITLE; ?></h1> </div> <?php echo tep_draw_form('checkout_address', tep_href_link(FILENAME_CHECKOUT_SHIPPING, '', 'SSL'), 'post', 'class="form-horizontal"', true) . tep_draw_hidden_field('action', 'process'); ?> <div class="contentContainer">   <h2><?php echo TABLE_HEADING_SHIPPING_ADDRESS; ?></h2>   <div class="contentText row">     <div class="col-sm-8"> <!--  If this could be applied *only* if the customer is NOT a guest ...       <div class="alert alert-warning">         <?php echo TEXT_CHOOSE_SHIPPING_DESTINATION; ?>         <div class="clearfix"></div>         <div class="pull-right">           <?php echo tep_draw_button(IMAGE_BUTTON_CHANGE_ADDRESS, 'glyphicon-home', tep_href_link(FILENAME_CHECKOUT_SHIPPING_ADDRESS, '', 'SSL')); ?>         </div>         <div class="clearfix"></div>       </div>     </div>     <div class="col-sm-4"> -->       <div class="panel panel-primary">         <div class="panel-heading"><?php echo TITLE_SHIPPING_ADDRESS; ?></div>         <div class="panel-body">           <?php echo tep_address_label($customer_id, $sendto, true, ' ', '<br />'); ?>         </div>       </div>     </div>   </div>   <div class="clearfix"></div> <?php   if (tep_count_shipping_modules() > 0) { ?> Thoughts?   Malcolm
