Walmart has jumped on the October Prime Day bandwagon in an attempt to sway you away from the biggest online sale of the fall. The main event is Amazon's two-day Prime Big Deal Days promotion, aka October Prime Day. Walmart Deals is meant to be the answer to Amazon's Prime Day sales. The sale happens every year around spring, summer, fall, and winter, revolving around Prime Day sales. Do you need to be a Walmart+ member to shop during Walmart Deals?
