A great way to find discounts at boutiques is to become a vulture of sorts.  Learn the retail patterns in your neighborhood, and recognize when stores are about to go under, when they are, approach the owner and offer to take inventory off their hands at a large discount.  One way to learn more about the dynamics of retail real estate is to get in touch with a local realtor who knows the area.  I have learned a lot of information from an agent who works at Metro1 Properties.  They specialize in commercial sales and leases in the Miami area and know very much about the local markets.  They know retail, warehouses, industrial, and office space.  I would recommend them to everyone.
