No problem. I always tell people to not rely on MLM/direct sales company because these companies their first priority is profit.

Not really. I recommend those people the product name. Up to them want to buy from me or buy themselves directly.
All MLM/direct sales whether you buy directly from the company or the distributor are overpriced. How I know? I was ex Cosway customer. Got it straight from the source.
Then I compared Elken/Amway (website price) vs straight from US, found that it's cheaper to buy myself than relying on those companies.

Even by buying from me, my customers already save at least 100% than buying from Cosway/Elken/Amway.

Agreed. One should research before buying.

Eg. Cosway NN Spirulina/Elken Spirulina/Amway Multivitamin

Did you know that Cosway uses the same spirulina from Parry Nutraceuticals (from India)? NOW is the cheapest company which uses Parry Nutraceuticals spirulina. Same product, different price. Just search online at Amazon and you can see the price difference. Now, you will be saying what about shipping? You can use direct freight forwarders and still save compare if buy directly from Cosway/Amway/Elken. Alternatively can buy online from online shops.. I myself save min 200% by not buying from Cosway. I use to take the NOW brand then I switch.  (I don't recommend taking the Parry Nutraceuticals spirulina)

For Amway multivitamin, just check with other good brand like Life Extension/Pure Essence (these 2 are way superior). Repeat the above. How much can you get discount? RM10-20 by being member? Even with that tiny saving, buying straight from US yourself is way cheaper.

Another example. Fish oil. Eg. Amway Salmon Oil. 120 softgels which contain 180 mg of EPA and 120 mg of DHA. For that same price you pay if you are member, one can get better quality and higher concentration from Carlson Elite Gems 240 softgels. Don't believe me? Let's bet. The omega 3 from carlson are at least twice Amway at 400mg of EPA and 300mg of DHA. It cost about RM260 (after shipping). Compare that with how much Amway is selling.

Then there's question about quality. No fish oil in Malaysia are certified to be clean from pollutants/fresh (not rancid) and meet the min amount as stated on their labels. Certain US fish oils are certified by International Fish Oil Standards (IFOS). For me personally, I only take fish oil certified by IFOS. The IFOS Program is the only third party testing and certification program for fish oils. IFOS sets the world's highest standards for purity, potency and freshness. If a certain product did not meet that standard it's unsafe to consume.

You want more proof? Just get me Amway's member price and I will get you an equivalent product at cheaper price.

I already save >RM3k by opting not to be Cosway member anymore.

No hurries. A perfect example is shown below.
Why amazon? Because there you will get honest customer review where they will compare other products. Items sold on lelong. mudah are not even worth looking at. All selling same stuff as those sold by Malaysian pharmacy. You can't even see the full list of ingredients on Malaysian online store. Yup. That's why you get the CoA, look at official company label to check out what's inside (in US, there's a law that the manufacturer must list out what he put inside. Cannot hide. If hide and found out, can kena sue. Don't need to list until exact mg just the contents).

Honestly, I don't take blackmoore anymore. There's so much better brand than Blackmore (Healthy Origins, Nutrex Hawaiian, Carlson, Nordic Naturals, etc)

Those products I get are genuine and expired min 2-3 years from purchase   
US stores buy in bulk so they are practically half price than what's sold by the official manufacturer. Supplements in the US are cheap compare to Malaysia.

You sound like Amway agent. 

I told you I don't sell Amway. You can check review on Amazon and see what people think of Amway.

Option (iii) and (iv) provide non acidic vitamin C. Now tell me again whether Amway is cheaper or more expensive. Even if it's selling at RM100, it's still expensive for a bottle.   

For me, I personally won't buy vitamin C supplements. Why? Better option exist such as lime, lemon, roselle. Why waste money on vitamin C supplement? There are other better stuff than vitamin C for immune/antioxidant.
