MarketPress: What is the custom post type for products?

Hi again!
I am trying to turn off the sidebar of the product pages (so I can make them full width), for other archives of custom post types on my site I would use something like the below, but I can't get it to work for these.

Any tips would be great!

// Remove original sidebars
function no_sidebars() {
if ('product' == get_post_type())
		return false;
		return true;
add_filter('thesis_show_sidebars', 'no_sidebars');

// Add a class for styling
function one_sidebar($classes) {
if (is_home()) {
    $classes[] = 'one_sidebar';
    return $classes;
add_filter('thesis_body_classes', 'one_sidebar');

And yes... I am using Thesis. thanks.
