Wah seh, thanks for the tip. Must bear n mind.
Well, I bought the sunblock and day cream and I had two bonuses. In
each bonus pack were cleanser, lipstick, firming creme, a rich nite
creme which she said to only use it in winter and something else.
Forgot liao. 
So, perhaps if I buy only when there is a bonus, I should get it
from here, right?
