The OtterBox Commuter Wallet For iPhone 5/5s is retailing for S$55 in Singapore. The case adds quite a bit of bulk to your iPhone because it gives your iPhone added protection against drops, bumps and shock. It also includes a slider compartment at the back that house up to 3 credit cards.

On the official website, it states that it can hold up to three cards and one bill, however when I tested it, it is not able to hold even a single note after placing 3 cards in (1x EZ-Link Card, 2x Credit Cards). I guess Singapore currency notes are bigger and thicker because of the materials it is printed on.
