Walmart is hosting an anti-Prime Day sale this year, though it's not explicitly advertised as such. Walmart+ Week runs from Monday, July 10 at 12 p.m. ET until Thursday, July 13 at 7 p.m. ET — a day before and a day past Amazon's event. Some fine print: The first 24 hours of deals are open exclusively to members of its Walmart+ subscription service before everyone else can start shopping at noon ET on Tuesday, July 11.
