u can remove ship to address from: components/com_virtuemart/views/cart/tmpl/default_pricelist.php
after that, here: components/com_virtuemart/views/user/tmps/edit_address u need to delete 2 more rows
but i can`t tell u which are the rows numbers couz i don`t have them anymore
and after that in languages change "bill to" whit "ship to" and ur good to go , but i don`t know where that file is couze i translate it in my language before instaling it
