Many of you have once or twice witnessed some stores selling our products at lower prices. 

The problem is that we supply only our officially certified partners with our products. 

There are gmarket, ebay, or amazon. There might be more and they're not our official stores. We can not find them all, either. 

Usually, they have nothing sotcked. Or they collect our products by buying some items used and resell them.

However, the condition of the products they sell might not be okay. 

We can not guarantee the quality of the products sold in various markets.

Most of those products expire soon. 

We also find some items are arleady delisted and in disuse. 

How can we guarantee the quality of a product that we already stopped producting 2 years ago?
