Guys, I don't know you realize or not, ppl who doing business in Msia roti canai ka, kedai runcit ka, even the big big business ( not everybody but mostly) are locking to the concept of PROFIT MARGIN meaning when the cost increase 1%, the price also increase ( mostly more than 1 %) because they want to maintain the profit margin, That why we the middle and low income always being threat unfair. This concept has become their culture since past past generation because they want to KAYA CEPAT. Compare with other country, they doing business using the concept of volume of sale- the more they sale the more profit they get and the price are lower compare with us. WHY because they think about long term. WHY CAN WE DO IT LIKE THAT IN HERE? I think if all businesmen in M'sia apply the concept of volume of sale, then this issues will never rise.But sadly I only a dog yang menyalak bukit, but bukit tak runtuh meh....
