Hi, i'm planning to get my J12 watch from overseas. Understand it's cheaper for me to get it there then in singapore. However, i need to know if it will be cheaper for me to buy from USA or Paris (europe)? As I know, if I buy from USA then there will be no tax refund but the retail price is already cheaper than in singapore? Ideally i wuld like to get it from Chanel Paris but not sure if the retail price is cheaper than in USA (but i can claim tax refund, do you know how much will that be??), thanks! Appreciate your help and comments on this!
