Highly doubtful, but interesting thought. Talking to the guys at Diapers.com, they want their customers to be happy the first time around. On the off chance they're not, they want them to be absolutely delighted the second time. I'm also pretty sure that the extra cost incurred by including the "mistake item" as well as knowing you're discretely increasing demands on customer service might make the customer acquisition cost not worth the lifetime value.
