Marketpress e-commerce page logic

By default, MarketPress seems to display content (i.e. product listings, product details, shopping cart, etc.) within the site's default page.php layout.

My page.php includes the ability to share content via Facebook and Twitter - however, I want to hide this for MarketPress content like the Shopping Cart, Checkout page, etc.

Is there a neat conditional that will allow me to hide elements on the page.php page when MarketPress is displaying the Cart, Checkout, etc.?

i.e. something like...

<?php if (!is_page('shopping-basket')) { ?>

<!-- stuff here -->

<?php } ?>

The above isn't working for me, so is there another conditional that I can use to identify when the Cart or Checkout pages are showing?
