Consumer awareness of supply chain shortages and even earlier deals may have contributed to a slight decline in U.S. e-commerce sales during Cyber Week — the kickoff to the holiday shopping season that runs from Thanksgiving Day through Cyber Monday. Last year, U.S. consumers spent a record $34.4 billion during Cyber Week, up 20.7% from the year prior. But this year, that figure dropped by 1.4% to $33.9 billion in online spend, according to data from Adobe’s Digital Economy Index.

Adobe’s analysis comes from data from over one trillion visits to U.S. e-commerce websites, which feature 100 million individual SKUs across 18 product categories, giving it a comprehensive window into holiday shopping trends.
