Millions of Americans are gearing up for the Fourth of July weekend. While the majority of grocery and retail stores will remain open, some locations may follow reduced operating hours. As Independence Day is a federal holiday, it is important to note that the banks, post offices, and federal offices will remain closed.

Call it Prime Day, or Black Friday in July, but this week is expected to mark a major moment for summer spending. Why it matters: Billions of dollars are projected to be spent at Amazon and other retailers that are running competing sales.
