I work in e-commerce and completely believe this could be true. The 'Cart Abandonment Bot' is actually something we just had a meeting on today, trying to figure out what's going on here.
With that said, what do you think the error is here? Could your script have had some false positives? Enough to move the dial?
Some sites won't give you the price or the shipping until you add to cart, but that shouldn't map to an automatic removal of item from cart (unless there IS a timer somewhere set to 4 minutes on the server side).
Strange that the item cost $47 and the number of sales was 47.
