One retail eCommerce store owner raises the problem of removing the line "shipping and taxes will be calculated at checkout", which may scare customers away when he already advertises free shipping on his site. If you have the same dilemma as his, you should do as follows: Go to Online Store > Themes in the admin panel. Select "Edit languages" from the "Actions" dropdown in the current theme. The text you wish to edit is under the "Cart" tab.
