From baby bibs to power tools, Temu offers some of the best deals on products in the world. That’s thanks to the company’s deep connections with top-tier global suppliers. But how does it keep costs so low compared to other big-box and warehouse stores?

NAD said the company could not substantiate that claim and should stop using it.
