How Is This Possible? Must be Counterfeits

I just stumbled upon this website and they have branded products such as Nordost and Audioquest at about 10% of the normal retail.  How is this even possible and if they are indeed fakes, how come companies like Nordost do not sue them? Truly puzzling.   https://www.aliexpress.us/w/wholesale-nordost.html?spm=a2g0o.detail.search.0
