For those not in the know:
Amazon prices fluctuate all the time.

Once a year, Amazon hypes up "Prime Day", where they make your savings over list price jump out at you to trigger a psychological reaction that says "I need to buy this now (before Prime Day is over)!"

These boasted savings aren't over the usual price. They are over the list price, which you usually only pay if you're unlucky in your timing.

Sometimes you'll end up paying more on prime day than any given item has been in the past. If you already were planning on buying a thing and it happens to be one of the Prime Day specials, great. On the other hand, if you're trawling through Prime Day specials to look for things to buy because they're on sale, well, there's a reason that Jeff Bezos was able to rent out an island for his fancy wedding. 😂

Thanks for this. I love that price / time graph.

Fuck you Bezos!
