Putting more than one card in each slot saves a lot of space. I returned a previous wallet I bought thinking it would fit all my cards and receipts but it didn't fit in my pocket! I also like the material: it holds cards well, but also fits well in your pocket. This one with the zipper is the best: keeps all the contents.
