Bought Saint Laurent bag from bluefly. When it arrived, the bag came with box, dust bag. The bag is new and authentic. The biggest problem was it didn't came with an authenticity card. Contacted customer service, they said since they got the bag from another company (rue lala), there's no way for them to get the card. That lowers the value of the bag. I didn't return the bag since it's authentic and bought it for a really good price.
