Man, someone should have created a trading desk around his refund policy. I'm not sure how much his product was (or what it was), and the returns don't compound, but still.
Perhaps you'd write into your terms of business that you could only have one refund per person per year or something like that to limit this sort of edge case behaviour.
I recall it being a sports nutrition business but selling something reasonably unique. I would estimate that it would be an average sale of $50-$100, perhaps a high of $300?
So long as you're making decent sales an occasional hit of $5-$10 and the even rarer hit of $30 is hardly terrible.
