Does retailmenot make $ on every coupon?

For a particular product, retailmenot links users to the company website of that product. When I search for that company's affiliate program, I can't find it listed anywhere.

Does that mean retailmenot doesn't generate any revenue from that page or do they go direct to the company to create an affiliate program or am I just not able to find the affiliate program?

They could mix it up, never seen the aff program so probably something got to contact them for.

They are working with companies directly it's like those websites that compare products
