Walmart is offering significant discounts, up to 50% off sitewide, during its Summer Savings Event, positioning itself as a strong competitor to Amazon's Prime Day. The event features deals on various products, including tech, audio equipment, and televisions, aiming to attract shoppers seeking alternatives to Amazon's offerings. This preemptive strike allows Walmart to capture consumer attention and sales before Prime Day officially begins, potentially impacting Amazon's market share during this key shopping period.
