Looria co-founder here. I want to clarify that we do not exclusively list products on Amazon. It just so happens that most products people buy are on Amazon.
It would be nice if you had an option to never show Amazon links in the results. Due to their commingling, counterfeit problems, and their scummy business practices, many people who would use your site probably don’t want to give Amazon their business. (I’m betting a higher number of your users are power users than other sites.) One of the features I like about kagi.com is that I can exclude sites from search results.
I try to go to the manufacturer’s website when possible. If that’s not possible, I try to go to a site that doesn’t have any other sellers on it. The whole “marketplace” that many websites are becoming is awful because you can no longer find a store you trust and buy from it knowing you’re more likely to get something of quality.
Anyway, I’m sure that doesn’t help you get revenue for your site, but since you asked, I wanted to respond.

Our price aggregation is a work in progress, but our goal is to list prices from any seller, regardless of whether there is an affiliate program.
Our backpack category has more places to buy for example: https://looria.com/search?&category.subcategory=Backpacks
