Today's show featured "Best Of Clark" repeats from recent shows

Clark is a frequent traveler, and it's not too long ago that he recalls people queuing up in airports at endless banks of payphones. The mad rush for payphones in the pre-cell phone days gave rise to a dangerous crime called shoulder surfing. Criminals would pretend to videotape family members near the gates, but they'd really be filming people punching in their long-distance calling card numbers. The crooks would turn around and sell those codes all around the country within minutes of filming.

The days of shoulder surfing are now long gone; payphones may be the next to go. AT&T has announced that it's getting out of the payphone business. There are some 300 million people in our country and more than 250 million of them have cell phones. The 50 million that don't is largely made up of children, such as Clark's 2-year-old son and his 8-year-old daughter. But while we no longer have to worry about shoulder surfing, we can still fall victim if our cell phones are stolen. Clark gets tons of calls from people who get stuck with a huge bill when criminals make international calls on their phones. So it may be wise to get your international long distance blocked. At the very least, be sure to report your phone stolen as soon as possible. That way you'll be able to avoid this costly mess. On a related note, Continental Airlines in Houston now allows you to check in with your cell phone just by showing your e-boarding pass.

Over the summer, Clark mentioned a service for airline customers called Yapta.com. Yapta lets you know if you're eligible for a refund or credit if airfare drops after you've made a purchase. Now that same idea is being applied to the world of retail. Many stores offer a price-protection policy. So if you buy something and the price drops within 30 days, the retailer may give you a refund. But who's really combing over circulars and online ads after you've made your purchase? Enter the magic of the Internet. There are a couple of free, ad-supported websites that will do it for you! They include RefundPlease.com and PriceProtectr.com. You simply enter the make and model of what you bought and they'll send you an e-mail if the price drops. PriceProtectr.com claims to have saved consumers more than $500,000, while RefundPlease.com says its savings are more in the $100,000 range.

Clark's executive producer Christa recently gave him an article from Health magazine that spoke about how plastic water bottles can leach Bisphenol-A (BPA), a chemical that's toxic in lab rats. So the inevitable question arises: Can it also harm us? Clark's not buying the leaching plastics theory, but he thinks you shouldn't drink bottled water because it will drain your wallet. Most bottled water comes from the tap, including Aquafina and Dasani. Just compare the numbers for yourself: Drinking tap water will cost you 40 cents/year vs. $1,500/year for bottled water, according to one study. Then there's the environmental angle: Between transportation, packaging and disposal, bottled water is an eco-disaster. If you're still reluctant to drink from the tap, try using an affordable filter. The Brita system was recently featured on NBC's The Biggest Loser -- a show that's watched by both Christa and Clark's other producer Kim.

Regular oil changes are a great way to ensure your car has a long and healthy life. Unfortunately, many people are susceptible to getting scammed during an oil change because they don't know much about their cars. The state of California has now reached a $5 million settlement with EZ Lube over such a scam. Customers would initially come in for a $25 oil change. But EZ Lube employees had quotas to meet and weren't allowed to let customers go until they billed them a minimum of $75 for unnecessary work.

Here's how to avoid becoming a victim: First, you need to know that most cars get major regularly scheduled maintenance every 15,000 miles. So when you bring your vehicle in for an oil change, just bunt when you're told you need some hardware or repair that completely baffles you. Pay for the oil change, make a note of what you're told you need and tell the person you'll get it fixed during your next major service checkup. Major service can be done either at a car dealership service center or at an independent shop that specializes in your brand of vehicle. Clark prefers the latter.
