The wait is over! Amazon's Big Spring Sale is officially live, and it's overflowing with some of the steepest markdowns so far this year. From now through March 31, you'll find mega deals across 35+ categories, making it the perfect time to stock up on essentials, gifts and splurges alike. But it gets better. In addition to seven full days of discounts, this shopping event includes daily themed deal drops to amplify your savings, unlike any Big Spring Sale before.
