Just to throw in my 2 cents...
Century21 has some great deals, but be prepared when you go into the store as it is packed with tourists and locals, all looking for the sale deals. It is very difficult to walk through and the shelves are a mess because people will take things and just throw it back. There are definitely deals to be had though - just make sure you sharpen your claws!
Jersey Gardens is ok, but does not have a whole lot of stores - one benefit though is that it is indoors so weather is not a problem.
Woodbury Commons is much better IMO, as it has more stores and also has high-end stores (i.e. Gucci) if your looking for a bargain in the luxury line. However, it is outdoors and the stores are a little scattered (you will need to pay attention to the maps so you don't miss anything).
have fun!
