First of all, to my knowledge, there isn’t an official store for ZZZ products outside of mainland China. Therefore, the “official store” you see may just be a claim from the seller.

As for the prices, while the products we sell on our website are all official ZZZ merchandise, we generally do not engage in marketing, which keeps our costs lower. The price you see is after we add a reasonable purchasing fee, along with procurement and shipping costs. Since there are only two of us and we don’t do any advertising, our costs are relatively low.
