Apple Computer seems to think that $50 is a fair price for a spare iPhone charger, so I headed off to Best Buy today to see if I could find something more reasonably priced. And I did. But can anyone explain this?

On the left, you can buy a power adapter plus a cord for $21.99. On the right, you can buy just the cord — the exact same cord — for $24.99. Surely there's a breakdown of the free market at work here. But of what nature, exactly?
