50% off of a new pair of raw indigo denim when you trade in your existing pair of raw indigo denim (regardless of fit), but they must be very warn in, we're talking torn knee's and epic fadez etc. They don't take that many pairs in from customers for the butler series and there's a waiting list you can put your name and details on for a specific fit and size.
Do they have to be apc raws? I have a pair of 501xx that are knackered.
Also, where are they made? I got an apc jacket from the mr porter sale but it was made in Latvia so I returned.
