This season amply generous sample sales have thrilled bargain-hunters. Among the best, Salvatore Ferragamo's sale, where clothing and accessories are up to 80% off. (Attention Italian parliament, our purchases alone probably constitute a bail out.) Just a few blocks away, Kenneth Cole is unloading their sleek basics at Lilliputian prices. Here are some of the sales' best bets. But hurry, Ferragamo's last day is Wednesday, March 4th, while Kenneth Cole's sale ends Friday, March 6th.
