Really appreciate how clear and direct the intro copy and image are in this Landing Page for Hypnax. Also note how the Buy Now pop-up shows all the checkout steps in one view.
This website has unfortunately been redesigned or gone offline, so I have removed the direct link to it. The screenshot below hopefully preserved enough of the design but if you are really keen to inspect further, try this Archive.org link. FYI: the site was first featured on 23 September 2018.
