In my opinion the navigations are to much. It would be nice if there were only one navigation with a clear structure where the user only sees navigationitems that might interest him or her. Maybe a sticky navigation, that way your users could navigate your page much faster regardless on where on the page they might be. It might also be nice to move the searchinput to this navigation, so that it is always prominent.
It would also be nice to add more payment methods. It's rather irritating and frustrating if you click the button "choose payment method" and there is only one to choose from. Furthermore, not everyone is in possession of a credit card.
To make the page responsive or at least to provide a mobile version could prove to be helpful, too.
