Original Source shampoos on discount

If you stay in Singapore, there's a discount on Original Source's shampoos at the Guardian shop (Shaw plaza, Balestier Road). The shampoos usually cost $8.50 at Guardian, and $9.50 at Watson. Now the special offer is $14.50 for two bottles. I just got 2 bottles - tangerine + bergamot and almond + coconut. The scent is really rich. Great time to stock up some and save some $ :)
