That's awesome. And I think it scales for just long enough, too. I don't think hiring real, intelligent humans to make on-the-fly shopping decisions like this (think, an old-school concierge desk at hotel) costs more than the incremental value they'd bring in. If 90% of the requests can be handled automatically, then you can afford to make magic happen (and delighted customers) in the 10%. It falls apart at a certain global scale, but I'm sure the business has pivoted twice by that point. Nicely done.
