Is postal service in Malaysia really that unreliable?

There is an online group-buying site being launched in Malaysia a few months ago, which has quickly became popular among local consumers - thanks to the heavily discounted retail vouchers being offered.

What does Group Buying mean For Retailers?

Group buying sites like Groupon continue to gain popularity in United States, Europe, Asia and all over the world. China itself has more than 100 Groupon clones, heck?

This resembles Facebook's early years to a certain degree, where everyone is trying to clone and develop some sort of social networking services.
