Bought the SwitchEasy Capsule Neo (black) case for my iPhone 3G for S$49.90 from GizmoSquare which is located at 102 Tanjong Pagar Road. I like the online store because I can pay by PayPal and then collect it at the physical store itself.
The opening hours on weekdays is from 12pm to 9pm, I went there at 5pm on Wednesday and I got a shocked that the store is closed. Before hand I emailed Curtis (the boss of GizmoSquare) and he told me to come before 7pm as he need to close early for the day and I did, I reached there at 5pm which is indeed before 7pm.
