Wow, really? The quality control is that poor...yikes. Perhaps I should look elsewhere for a wallet? I had my eye on a Kate Spade, but the problem is that I am very choosy and cannot seem to find a wallet I like with twelve cc slots!
I'm not familiar with Kate Spade, but don't worry too much about the Coaches. A trip to one of the outlets is always your best bet if you can manage it, but most of the wallets are very good quality.
And you probably already know that there are fake Kate Spades too, so nothing is really safe. Even basic brands like LeSportsac and Kipling are faked, though not so much with wallets.
