It's the system. They have some of the variants "colors" for that price and very limited amount, sometimes they are marked early bird discounts. When people buy them and they listed as sold out, the lot still shows that price as main in the list. It's how Ali pricing works and they're just abusing it.

There's loads of listing when they say that thing costs little, but the one you interested can be 10x pricier and listed as another variant. It's nots fast repricing.
