OK, here's a secret "the man" doesn't want you to know. Some companies have a toll-free number that's buried deep on their website -- but it would take like a thousand clicks to find it, and these days, who has the time? One way to get to it more quickly is to search Google for the company name and the phrase "customer support." Like this: Apple Customer Support.
An even trickier way to get at hard-to-reach customer support phone numbers is to search for the company name and the standard toll-free prefixes. That'll dig up some real gems. For example, "[company name] 800 OR 877 OR 888 OR 866". Give it a whirl -- and here's to less holiday stress.
