8 miles per dollar (mpd) is one of the highest number of miles that one can clock in Singapore, and that will actually help accelerate the rate of miles accrual, so that you can exchange for a free flight to your favourite destination!
Every now and then, Lazada and Amazon will take turns to have this promotion with Citibank rewards credit card, where you will receive 8 mpd when you pay using the Citibank Rewards Card. Do note that there is a cap of 20000 Citi Dollars per statement cycle for this promotion. Full T&C available here.
