expired Wireless Mouse varieties starting from $8.88 @Officeworks
As you can see, there are variety of keyboards and mouses available on this catalogue. Starting from 13 to 137 USD, pick your keyboard. If you are a serious gamer, don't miss out the G213 Prodigy. Very good deal to catch this week. If you are a smart TV guy, K400 might be a better choice. This one includes tiny touchpad on it. You can control any smart TV with Bluetooth support. Connectivity is much easier on newer models. You can even consider attaching it to Android phone. As for the mouse products, X4500 is my fav. I think it's universally comfy type mouse. Fits perfect to all hands. Sensitivity is precise and it's my recommendation for both gamers and casual users.
