I recently bought a blood pressure monitor from Amazon, and it took two days because I couldn't buy it at work, can't buy it while driving, couldn't get it at the gym, and was too tired to look into it when I was at home.

The idea of an agent, not owned by the store (who may try to upsell me) that could look into the product and buy one sounds great. Instead of waiting two days I could have just told the AI to run the errand for me while I was at work. I don't know anything about blood pressure monitors and I don't want to learn, so as long as it's <$50 any choice is fine.
