Dear DT1, you are right. Nordic Naturals are expensive but NOT VERY expensive. I compare to brand like Blackmore, Nordic Naturals are cheaper. For example I bought the 16oz fish oil for my 2 children (liquid form), it lasts 3 months. The premium fish oil for adults (8 oz liquid) also lasts for 3 months as the consumption only 2.5 ml per day.
Previously I bought from Singapore and Swansonvitamins (use USA forwarder), it's very expensive because of the shipping charges. Now I order from iHerb.com, it is much cheaper because they give very big discount on shipping (DHL). The fish oil come to me in 4-5 days.
First order purchase can get extra USD10 discount for order above USD40, or get discount USD5 for order below USD40. Just use my referral code JZG052 will do (you can use other code, no problem).
Now I even order baking flour (gluten free), snack bars, hollywood diet drinks from iHerb because the DHL shipping getting cheaper and cheaper if you average out.
My advice is to use DHL, not the FREE USPS postage because you may find it too long to receive your parcel. Sometimes can go missing because of our POS Malaysia misplace of parcels.
What I meant is, you can find the ingredients of similar quality in brands that are potentially cheaper. For example, tell me if Source Naturals's Arctic Pure Fish Oil works out cheaper for you after considering the EPA/DHA content.
