I'd also add:
* Additional _extremely_ hidden costs.

E.g., assume your Concierge AI starts adding tons of things to baskets to see what the costs are and rejects anything that is >x, as instructed in the scenario, then we might see tricks employed to hide costs until after the AI decides to buy.

Or it leads to more mass price fixing and gouging practices -- except this time semi-automated by computers.
