It was a flea market to dream of: The 2nd Annual "Super Saturday" Family Benefit for the Ovarian Cancer Research Fund, in Southampton, N.Y. Designers Donna Karan, Nicole Miller, Vera Wang and even ex-Seinfeld squeeze Shoshana Lonstein, among others, were there to offer their wares at rock-bottom prices (all for charity). Not that everyone was after a bargain. Kate Capshaw (Mrs. Steven Spielberg) told PEOPLE's Michael Sommers: "I grew up without money, so for me anything that was half-price felt like something I should have had the first time around. I find I have this odd response to sales . . . I insist on full retail. No one can give me a bargain."
