Century 21

If you're ready to brave the crowds for a bargain deal, consider Century 21 the answer to your shopping prayers. This megastore is known by New Yorkers as a top spot to find high-end, designer brands at bottom of the barrel pricing. The catch is that the store is often a madhouse, so you'll need heaps of patience and a love of digging through disheveled displays to find your gems. Don't plan on going if you're short on time. Instead, make a day of it and go in with a battle plan. And look at it this way: even if you don't find your sister a sweater, you'll surely walk out with a story for the dinner table.
