I'm very concerned about the idea of about giving LLMs access to my credit card, but this is the kind of future I want. I prefer to buy products directly from manufacturers, but I keep going back to Amazon. Amazon's experience is pretty bad in many ways, but I still get value out of the fast ("free") Prime shipping, and Amazon's ability to aggregate products across different categories and manufacturers is still a strength. I would love to be able to just type "buy me a FooCorp BarBaz" into an LLM, and have it take care of choosing the retailer based on whatever criteria I've decided, whether that's lowest price, best return policy, fastest shipping... whatever. That sounds like it could be a much better experience than what we have now. But I do worry that a service like yours could be biased in myriad ways, and an unscrupulous owner of such a service could do shady things like allowing retailers to pay to be preferred over others. Ultimately I'd want the open source version of this that I can self-host.
