>>>Sir this product has a lot of listings, if you search on amazon there are above 60 listings, that means the day you will launch the product it will be somewhere between 3-4 page as Amazon show 15 products a page.
So even if you do better listing and get friendly sales and reviews then also you will hardly go to page 2-3 as in first 2 pages almost all the listing have reviews. But unless you are not getting your product listed on page 1 it will be difficult to get sales.
As for the new seller, it will become difficult to fetch good margin. We are uploading October month eBook within a couple of hours you can find a potential product from there.
