if you buy 5 CD or more is worth take a $20 cab to 金海印广场南方 that is the lowest price in CN
Exspecially if you buy bricks or TIS 1:1 direct , as least save you $30-60 each
海印 is the choice in GZ。alternatively go to 新华书店(体育西路), but choice is limited and wonder whether you will walk to there, taxi driver will X%@ if you take his car, I guess you reside in Westin or Jianguo
