Everrich is a duty free shop nation wide in Taiwan.They have duty free shops at all airports in Taiwan. I bought double black label whisky from them cost me Ntd1110 a bottle. I have receipt for it. Yesterday, I went to local supermarket they are selling for ntd999 Difference of ntd111 more than usd3 a bottle. Duty free suppose to be cheaper than the market price. I am surprised and shocked.
