Temu, which runs an online superstore for virtually everything — from home goods to apparel to electronics — unveiled a commercial during the Super Bowl that encouraged consumers to "shop like a billionaire." Have you heard of Temu?

Do you use apps to shop online for any of the following?

A woman's swimsuit on Temu costs just $6.50, while a pair of wireless earphones is priced at $8.50. An eyebrow trimmer costs 90 cents. These surprisingly low prices — by Western standards, at least — have drawn comparisons to Shein, the Chinese fast fashion upstart that also offers a wide selection of inexpensive clothing and home goods, and has made significant inroads into markets including the United States. Have you ever bought anything from Shein?
