Big Discount on MyProtein.ru

Hello! I can order very cheap goods from the site of the English sports nutrition brand MyProtein.
With the information you buy, you can order much cheaper than, for example, right now on their website.
Let´s say on their official website (including all discounts) Omega 3 fish oil costs 825 rubles, and I was able to buy it for 550 rubles. How did it happen?
I am currently reselling MyProtein products.
Pay attention to the entire catalog of goods: https://ionbio.ru - and compare prices with MyProtein. You will notice that many of my products are cheaper than on the official website. Question: how did it happen? I´ll answer it :)
