It is, but it means engineering your formulations carefully before giving them to the computer. Computers taking things literally isn't new, but there's normally less on the line when we do it.
Also I would imagine that as often as not there would be an opportunity for human judgement. Maybe there's a _much_ cheaper one at 3.98 stars, or the 4+ star and next day delivery options are 3x more expensive than the next available option. In both of these cases a human with the right intentions would likely stop and do something different.
