I think that the main reason you loose time is that the products that pop up on the main page are not related to your search. There are many such pages that come up and we have to close them and that results only in the wastage of time. The solution that you need is to make a quick search without landing on the unwanted pages. I would suggest a tool for you that would give you
faster browsing and will help you to select the products in a time zone. This will enable you to browse the different pages that a link holds in a single browser window. You can quick download this free tool from
here.
Hope this will be your solution!!!
