You may also want to add a way to undo the copy in case of mistakes.
Such as on click, first check the button caption. If it is like "Copy Shipping Address to Billing" then do the copy and change the caption as in "Delete Billing Address Info". A subsequent click finds the caption to not be "Copy..." so you set the second group of address controls to "". There are other controls you could use as well, such as an option or toggle button, though I'd favor the toggle last I think. Then you'd alter a label instead of a button caption based on whether the option value is true or false (-1 or 0).
