Online license agreements usually have warranties that are WRITTEN ENTIRELY IN CAPITAL LETTERS. This is an anachronism from the typewriter era that should be avoided according to the 9th Circuit, a leading author on contracts drafting and the deputy GC of Wikipedia.
9th & 4th Circuit Courts of Appeal
Lawyers who think their caps lock keys are instant "make conspicuous" buttons are deluded. In determining whether a term is conspicuous, we look at more than formatting. A term that appears in capitals can still be inconspicuous if it is hidden on the back of a contract in small type. ... Terms that are in capitals but also appear in hard-to-read type may flunk the conspicuousness test. A sentence in capitals, buried deep within a long paragraph in capitals will probably not be deemed conspicuous. Formatting does matter, but conspicuousness ultimately turns on the likelihood that a reasonable person would actually see a term in an agreement. Thus, it is entirely possible for text to be conspicuous without being in capitals. (bold emphasis added)
There's also a 2009 4th Circuit decision that discusses an all-caps warranty disclaimer at para 922:
But the placement of the disclaimers (buried in a sea of same-sized, capitalized print), coupled with the absence of any cautionary language on the first page of the policy illustration, which contains the deceptive language and figures indicating Powell's out-of-pocket payments will "vanish," preclude a determination the disclaimers are adequate as a matter of law.
