I have 6 indexpages like this
and 2 more like the last 2.
This structure I did for more than 10 ago.
I am going to redesign the page for bigger and smaller devices, so I am seriously thinking about rediret the sales/index.htm pages to the level before that is about rentals. i.e merge them together, I think the user would have a better experience not having to jump between 2 index pages.
However I wonder if the pages would benefit beeing less deeper pages, or if the contrary, its good to have deep pages.
