Deactivate navigation menu on a single page

I have many pages on my website, all of which have the default header menu that is allowed with the theme I’m using, as well as the navigation menu I have in a widget in the sidebar. I have a sales page that I would like to bring visitors to that DOESN’T have any navigation menu, so visitors cannot be distracted or encouraged to click away from the sales page. Is there a way to deactivate menus on that one page only?
