First, PC World was right at 3000 NT coupon, but later Dell Changed their mind to 20000 NT.
Second, the 20000 NT coupon will only be valid if you buy the same model E4300, sounds good for 69000-20000 right? Wrong, because Dell over price the laptop. People can buy the same laptop from retail at around 40000 with discount, so dell is trying to play the game while make a lot of outrage people.
Third, Dell doesn't care about Taiwan branch since it's small, which make people so mad in Taiwan. Dell paid way much better when the same thing happened in china a while back, because that's where the cash cows are.
