This is pretty normal for buying
from random Chinese companies directly.
By our standards they are "cheating" but really it is a completely different business culture, all operating on razor thin margins, customer-facing staff that speak English
cannot support their customers, have no status, not encouraged to ask questions or take initiative, technically competent staff not allowed to communicate with the outside rarely speak English
, 99% of the time the staff know very little about what they're selling etc etc.
So yes you can save a lot of money
, but understand it's a roll of the dice if you get what you pay for.
When you don't, just like a lost
bet gambling, never mind try again.
Or, only deal with known-trustworthy sellers recommended by people you know you can trust, preferably located on the same continent as you and part of your culture.
But realize they have to charge a **lot** more than the chinese seller even selling the same exact product. Their company costs are much higher, any level of support, keeping demanding customers happy is super expensive, and they have to eat the risks when a container load turns out to be faulty.
You can't have your cake and eat it too.
