What are some marketing and rewards based business models that go well with shopify stores and apps?

I am managing a small catalog of home and garden products through some usual marketplaces, such as amazon or similar to it. And as I imagine is very normal the cost of fees and advertising limitations makes me think there could be some complementary options to move merchandise, but the notion of simply opening and store and assign a budget to it does not seem very appealing by itself.

Are there any business models that are codes, commission, and rewards based that could fit well? Does anyone have any examples of successful alternative business models? I am thinking Gymshark by using codes, or affiliate marketing like amazon, but applied to a small business through shopify. What are some resources or examples of all the options out there without going so far to the MLM extreme? Thanks.
