Zappos division 6pm.com screwed up and then manned up, making a mistake that capped all prices at $50 but honoring the sales and losing $1.6 million. The company blogged about it — apologizing, even — and then Zappos CEO Tony Hsieh tweeted about it. The king of customer service — whose book, Delivering Happiness, is coming out in only two weeks — set the bar high for screwing up publicly.

: I note that the original 6pm post was on May 21 and Hsieh’s tweet was today, the 23rd. Hmmm. Thinking they wanted more PR to make the mistake pay off.
