Sethi, author of the I Will Teach You To Be Rich blog, and book of the same name, notes that most credit cards extend purchase warranties to one year automatically, on top of the 30- or 90-day standards included in the box. Car rental insurance is also included in most card policies, and even if the airline tries to stiff you for a "late cancellation," many credit issuers grant their users $1,000-$2,000 per year in trip cancellation paybacks.

Sethi details these perks and others in a recent CNBC appearance, along with a free book chapter and related posts linked below.
