Found out about a good website to get all your supplements much cheaper compared to getting them from Singapore stores and it ships right to your doorstep. They sell all sorts of supplements such as Vitamins(Calcium, Fish oil, Vitamin c etc.), Hair/Collagen products, Castor oil, Manuka Honey and many more.

Currently, they are having a sale promotion starting now through May 31st:
5% off orders less than $59.99
10% off orders $60.00 & above

To get even more discount for your first purchase, use code SSM037 to save $10 for orders above $40 or $5 if order totaling less than $40. Hope this is useful.
