I didn't get a chance to go to the store where I bought it but the store I did go to had two in stock so the SA didn't even skip a beat and gave me a new one. Pointed out that this is clearly a flaw and told me not to worry about it happening again....we'll see.
I am glad you got another one! I was too paranoid to do it. But if you aren't crazy like me, the bag is so beautiful that it's worth keeping because if you return it ... no more beautiful Caissa. Now I'm totally lost as to what bag I want next!
