Some of those customers have been suing Zappos, an online shoes and clothing retailer that's owned by Amazon.com. Zappos wants the matter to go into arbitration, citing its terms of service. The problem: A federal court just ruled that agreement completely invalid. So Zappos will have to go to court—or more likely settle to avoid those legal costs.
