As per another thread, they are sending them to people who shop more at the outlets to entice them to shop in the full price boutiques.
Normally, they don't send the PCE cards to the customers who only shop in the outlet. Sales are sluggish right now and stock is way down. They're pretty desperate to get full price store sales which don't do as well as the outlets.
On the back of the card it said the discount is only on Winter 07 items or something like that and doesn't include special orders. Maybe I read it wrong or i'm just crazy. Theres so much stuff I want to get.
