If you go to amazon, click on the prime day banner, and scroll to the bottom, you can see a preview of when and what is going to be offered (but not the discount) under the "today's limited time deals." All the ones that are listed as "for prime members" are the prime day deals. I can see up to 7:00 AM (central) for what deals are available.
So much for secrets... unless there will be even more additional surprises throughout the day.
One thing I've noticed from BF events, is they pretty typically have at least the majority of items be popular, highly-rated items from their categories. I bought a high-end Paragon popcorn popper as well as a Uniden radio for the lowest price for both in years a few BFs ago.
Depending on how cheap it is I'm thinking of picking up that Clore jumper pack. I used to work at an Auto Auction and we used those things daily just non-stop. They were pretty handy. I wonder what the quiescent draw on it is. As long as it's low I could maybe just keep it charged up in my car for whatever happens.
Amazon Prime day was the biggest marketing scam I've seen in a long time!!!
Very few (if Any good deals) & just a way to sucker you into Prime membership!
