Nothing! And I actually asked my SA as I thought they're giving away something for the holiday season.. And she had no clue that other LV stores are giving gifts... I think it really depends on the location..
My thoughtful SA gave me a steel cube LV dice game. They're quite heavy and could probably be used as individual paper weights or display item... Always get the star treatment at my favorite boutique... Most times have sit down shopping and beverages offered... I really love the service at LV in Tokyo!! If you're ever in town, I'd be happy to recommend the best LV SA!!!
