This is a fantastic idea. All the benefits of Amazon (fullfilment, prime shipping) but with a better user experience.
Now that I think of it.. they do experiment with things like this. For example, near the top of my Amazon homepage right now, I see "Influencer fashion finds". Clicking in reveals some kind of modernized QVC social media livestream experience.
Further down on the homepage is a combination of what appears to be algorithmically curated shopping lists, and human curated lists.
It's all very messy and disorienting to navigate, but I guess they're.. trying?
