Where can we purchase affordable organic food in the market?

You can check out Xenzin, they carry a wide range of fruits and veg and is located at pasir panjang wholesale centre. (http://www.organicdelivery.sg/) If you're looking for dried products (coconut oil, chia seeds, oats etc) and not in a hurry, you can check out iherb (www.iherb.com). They are base in USA but will ship internationally and shipping is very affordable.
