Clark is a confessed warehouse club maniac. He joined his first club back in the early '80s. At one point, he was a member of all five clubs that operated around the country. Anyone remember Price Savers, Pace Membership Warehouse or Price Club? Some of the ones that used to exist have since been absorbed by competitors. Today we have BJ's, Costco and Sam's Club. Clark, of course, is a member of all three. He likens them to having children; it's impossible to pick a favorite one. When pressed, Clark thinks that Costco is first among equals. In fact, he loves it so much that sometimes it can be an exercise in excessive spending for him. So he's developed his Costco rule, which states that he doesn't get a cart and only buys what he can carry in his arms. When he brings his 2 year old in a stroller, he'll sometimes hang a small number of items off the stroller too.

There's no doubt that Costco is habit-forming. The New York Times reports that the power elite in Washington, D.C., have become frantic Costco shoppers. The Costco by the Pentagon has become the "in" place to shop. Republicans and Democrats can't agree on anything, but they both look for a deal at Costco! Another new trend in D.C. is to hire a caterer to prep food items that have been bought at Costco. Clark's son, meanwhile, thinks the sole purpose of going to Costco is to get a hot dog for $1.50. That's one food item that never goes up in price at Costco. People may revolt if that ever changes. Meanwhile, Clark's producer Joel thinks that IKEA offers a better deal on dogs: two for $1!
