I want to remove SKU from all email to customer
1) I create folder and copy file to not edit core
/app/design/frontend/my-theme/default/template/email/order/items.phtml
2) Delete this code
<th align="left" bgcolor="#EAEAEA" style="font-size:13px; padding:3px 9px"><?php echo $this->__('Sku') ?></th>
but Sku is still showing on email
What should I do..?
