How to profit from someone else's financial mistake | The State: Most of us have wasted money on ill-considered purchases or stuff we really couldn't afford. As we get more financially savvy, that happens less often. But we can still profit from other people's bad choices.
People who prize the latest and greatest, for example, quickly need to upgrade to the next shiny thing. That leaves plenty of lightly used cars and electronics for sale at a discount.
People who can't look beyond cosmetic damage also provide buying opportunities for those who can, since surface flaws can ding price without hurting functionality. Then there are the "d'oh" mistakes: the stuff that didn't fit or turned out to be the wrong shade of robin's egg blue. That stuff gets returned so it can be discounted and snapped up by frugal buyers.
