Nope, you can't! Just like Iluvbags said, LV is always excluded from all discounts. Wanted to use a coupon once and couldn't! Chanel, on the other hand, is different but that wasn't your question!...)
my SA at saks says she could get me a 10% discount if I find a family member to open an account. She had always went the distant to get me a good deal but i doubt her on this one...but i might just have to test her and see! *crosses fingers*
