看來IT部門很重要啊， 我發現， 洋店裏說buy2for$$， you do not have to buy 2 to get

saving, buy one is the half of saving price. But if you see this sale in Chinese grocery store, like 大華和永和， you have to buy 2, other wise the saving will not kick in. I was thinking about this, and I thought it might be the consumer law to prevent this to apply, since Chinese store is not the big target, so they can get by the law. Now I know it is the the software thing....nice inside info. Thanks for your posting!
