I love outlets.
tip #1. go to the clearance racks first. This is where clearance items for the real non outlet stores are sent (this is especially true for the polo store there, i get black label polos for 30 bucks and RRL jeans for 50 bucks there, made in italy polo chinos, etc)
tip#2 look at the racks in the changing rooms, this stuff was already deemed "good enough" by someone else and the chance of finding something awesome is pretty good.
tip#3 if your a AAA member, go to the main office and get a coupon book with some sick coupons.
Oh and a lovely (read: homely) woman by the name of Courtney works at the Brioni outlet and will usually give you a great deal if you joke around with her for a bit. (30% off an already 20% off brioni suit, unmarked 25% off full priced slacks, etc) bring the charm, cause most of the designer outlets are and will be able to negotiate a price.
