Need Help Developing a Value Ladder! Any ideas?

I am about to finish building this website that I have been working on for a little while now. The website is an aggregation of Amazon lightning deals that offers the user much more flexibility when it comes to sorting and filtering or simply monitoring the deals. Each product on my website is linked to the product on Amazon with an affiliate link.

Although this is the only form of monetization that I have devised thus far, it would be nice to have other methods of monetizing the website. The original idea seems sufficient to get people in the door, but what else can I offer them once they are at my website?

I thought of also scraping the top five products in each corresponding category of each deal item, and then displaying or linking to the those five products in each deal listing. Most of the top five products will not necessarily be any sort of deal, thus my margins will be higher on these particular items.

Besides that, I am stuck when it comes to creating a value ladder for this website. I have sat with the idea for days now, but cannot for the life of me figure out higher purchase items, more expensive products or services that I can offer the user.

Any input whatsoever would be greatly appreciated.
