This fuzzy math that Laurie found at Office Max seems like your everyday pricing error– a stupid sign posted by bored and underpaid worker who doesn’t bother to question authority. But look deeper. That sign says “As advertised.” That means that Office Max put out a circular or other advertisement bragging that they’re selling correction tape for one cent more than they normally do. Grab your coat, honey! We can’t possibly miss this once-in-a-lifetime sale!
