Ok, I'm usually a Gucci girl but today I bought my first piece of Louis Vuitton in over 7 years. It's just a simple zippy wallet, but I love it. When I got it home I looked for stamped serial number, but I can't find one. Is this normal? I'm also glad I went for the wallet because the SA told me the prices were going up next week. She didn't know what items would increase in price, but that prices would go up 4-10% on some items.
