Shoppers across the nation flocked to malls and major retailers Friday in search of "Black Friday" deals. About 158 million people were expected to shop in stores or online between Thursday and the end of the day Monday, according to the National Retail Federation.

Why it matters: Retailers hope a desire to return to holiday traditions will translate to big spending during the annual post-Thanksgiving sales events, even in the face of supply chain issues and rising prices due to inflation, as Axios' Hope King reported.
