U.S. retailers are extending Black Friday discounts into weeks-long sales events to sustain consumer spending as economic growth shows signs of slowing.

Consumers remain cautious amid persistent high prices, even as inflation eases. Black Friday through Cyber Monday is crucial for retailers' annual revenue, with strong but cautious spending expected as households remain financially stable. Economists warn of potential inflation spikes and slower growth if Donald Trump reimposes tariffs.
