Clark's cheapness has set off a couple of recent firestorms. Syndicated financial writer Greg Karp recently wrote about Clark's use of a single 17-cent razor for a year. Last March, Clark graduated to his second razor. But spending 34 cents on blades for two years is pretty good, don't you think? Yet many people have expressed that they think this is cheapness without a purpose because his razors are so cheap to begin with. In a way, Clark agrees -- but he'd definitely be saving a lot over time if his blade of choice was an expensive one. Other people are upset with Clark over the Zenni Optical issue. For those of you who don't know, Zenni provides deeply discounted prescription eyeglasses starting at $8. Clark himself wears progressive lenses from Zenni that cost him $41. But some people wonder how they can be any good if they're so cheap. Clark's friend Jim Strickland, an investigative reporter for WSB-TV, recently did a story about eyeglasses where he compared Zennis and a number other more expensive brands. The Zennis had perfect prescriptions versus the glasses that were filled at well-known optometry chain stores. The message here is that buying cheap glasses does not automatically mean you'll get bad quality. Consumer Reports recently revealed the three best places to have your eyeglasses prescription filled: At an independent practice where the optometrist has his or her own dispensing operation; at a Costco location; and at the For Eyes Optical discount chain.
