I tried the same thing, and it took me almost half an hour to realize that there was a "prime day" category in the search bar available for usage (although I also blame the UI for not making that more obvious). Of course, once I searched, there wasn't anything I was interested in anyways.

I was too, they are under gaming tech or something. I found 3 but 2 were super wide aspect and the other wasn't a deal I couldn't beat any other day.
