Walmart
Walmart's 1st of 3 online BF events will go live at 7pm ET. If you belong to
Walmart+, you'll get a 4-hour head start at 3pm ET.
Walmart+ is somewhat similar to Amazon Prime, but much worse with far fewer perks. Cost is $98/yr or $12.95/mo. There is a 15-day free trial, but it doesn't qualify for early access. Go figure.
For details about dates, links to BF ads and items on sale, please see
Walmart's BF post.
