IIRC Temu makes its business from super cheaply priced items.

Super cheaply priced generally means either super cheap quality or some really iffy labor rights violations* in third-world countries (I know that term isn’t the term to use nowadays since it’s a cold war relic but I can’t think of a better term—lemme know if you know of one), usually both.

*Up to and including slave labor. (Yay capitalism!)
