hmmm...I got saw Cartier shop at airport before, but can't remember which airport. Or if you got time you can go KL Cartier, i check the price before it can save a bit, for mine can save up to S$300+ per pair. But i got no time to go KL and go there need to spend as well. So before you go down, you can check from the Cartier website ask for price, if you feel worth it then you can go KL to buy. Other than this I didn't heard Cartier got gives discount or promotion.
