So this is irritating: Last week we bought nine 20-ounce Diet Pepsis, marked as part of the Pepsi/iTunes promotion, but found only one of the bottle caps was a winner. We felt a bit like the guy in the Tom Stoppard play who keeps getting heads when he flips the coin. We guess this is a bug in a promotion like this—that since the odds of winning are so good (they’re 1 in 3), it’s easier to get on what feels like a losing streak. Of course, having said that, the odds suggest that our next three bottles should all be winners, which gives us some hope. Hmm … why do we find ourselves wondering when the next bus leaves for Atlantic City?
