I've really been looking for something to trim down my wallet, and subsequently trim the cards and general "stuff" I carry with me.  Very very happy I bought this.  Space for my DL, debit card, and two credit cards.  You might be able to fit the occasional bill in the center pocket, but I'm going to bet that most people looking for this wallet are, like me, trying to eliminate the fact that they carry cash in the first place.
