"As you can see from the screenshot snippet above, Zappos' terms of use says "We reserve the right to change...these terms and conditions at any time." Zappos isn't the only website using language like this; it's ubiquitous on the Internet. Unfortunately, despite its widespread usage, this language is toxic to a contract." Isn't toxic to strong a word here? That particular clause it unenforceable, but the rest of the contract is unaffected, because of (I presume) a severability clause? The article seems to indicate that this clause taints other aspects of the contract.
