I'm embarrassed to say when I put it in my cart, it still had the $60 Prime Day discount (and a note about only "14 minutes remaining").
Then I got distracted, hurried back, added two more items I needed for this thing (a keyboard and an HDMI female to male cable, which I later realized was already included, but I wanted a higher quality one anyway), completed the purchase, then wondered why I am paying full price...
Luckily, I went on about an hour later, saw it was ON SALE AGAIN for prime day, was able to cancel the original order and got my $60 in the end...
