How do I remove WP sidebars from Product Pages only? (Marketpress)

I just installed Marketpress and I'm busy creating product pages. I want to remove my WP sidebar from these product pages. In creating a regular page within WP, there is an option in the right sidebar to disable the sidebars on a particular page. However, this is not an option when adding a new product with this plugin.

Any thoughts on how to remove these on each product page? Thanks for any help you can offer.
