Thank you everyone for your inspiring stories! Unfortunately they wouldn't give me store credit, but they did send it out for a repair. The sa said that is their first course of action and if it happens again they'll re-evaluate. I was upset after I spent that much money, and only had the bag for a short time before it was damaged, I thought store credit wouldn't be a problem. I called the 800 number and was told that store credit isn't typically their first solution. Ok fine. The guy from 800 said he had never ever heard of a crack in a mahina. He said that very rarely, but every once in a while a purse is sent in for repair and once they see it they find that the purse was not made right, is deemed defective and un fixable. I wonder if this is my case because both the sa at the store and the 800 guy were very surprised by it. He also told me he was surprised I was not charged for the repair! I was already so upset so I'm glad they didn't even suggest that, I would have been so furious!
Thanks for all your kind words! Not entirely an unsuccessful day, just not what I had hoped.
