Google Chekout Only disable regular checkout?

So essentially I want to rely on only Google Checkout to process all of our orders. How do I remove the zencart "checkout" link all together, so that cst must choose to use only Google checkout?

the site is Blue Wallace Project

Turn others off in the admin

I did that, but the checkout image was still showing and linking to the checkout page, so I deleted the image, then the "alt text" was still showing up, so i removed the alternate text from header.php and from something else, but that took care of it.

Open the file "includes/templates/template_default/templates/tpl_shopping_cart_default.php" and comment out line 131 so it looks like this:

<!--bof shopping cart buttons-->
<!--div class="buttonRow forward"><?php echo '<a href="' . zen_href_link(FILENAME_CHECKOUT_SHIPPING, '', 'SSL') . '">' . zen_image_button(BUTTON_IMAGE_CHECKOUT, BUTTON_CHECKOUT_ALT) . '</a>'; ?></div-->
<div class="buttonRow back"><?php echo zen_back_link() . zen_image_button(BUTTON_IMAGE_CONTINUE_SHOPPING, BUTTON_CONTINUE_SHOPPING_ALT) . '</a>'; ?></div>
