shift toward online sales
fewer retailers participating
end of holiday promotions
decrease in total spending

Explanation:

The rise of e - commerce has led to a significant shift in shopping behavior. Online sales offer convenience, wider product selection, and often better deals. Retailers have also adapted by promoting online Black Friday sales. Fewer retailers participating is not a major trend as many still engage. Holiday promotions continue, and total spending has not shown a consistent decrease but rather a shift in where it occurs (online vs. in - store).

Shift toward online sales
