I was at the WI Dells outlet the day they opened, and they didn't have any boutique merchandise in yet. When they opened they had factory-only merchandise, so I don't know if stores transfer directly to outlet or what, but ours had nothing notable to search for. They only had the merchandise that every other outlet would stock, too.
While that is great, I go to outlet searching for treasures. I go because they have different things every time I go (from returns or transfers and deletes). So the opening day just wasn't very interesting for me. Maybe other outlets are different - especially in larger markets - but I was very disappointed in the opening day at ours.
