Already mentioned but I’ll second https://isthereanydeal.com/ as existing.
That said, Valve has a fairly generous refund policy and the real kicker would be if Valve would automatically give you the better deal if the price drops within the refund window, backed up by such a feature. I heard them doing that before but it was only special cases, iirc, and the period is only 14 days but still.
Firefox addon: https://addons.mozilla.org/en-US/firefox/addon/steam-database/
Shows information directly on every page for game. I customized the settings and for me the most relevant information displayed are the lowest recorded price and how many players the game has.

… obviously. They run the platform. They could do lots of things.
feel like valve is retaliating against the gaming industry for its bad behavior recently
Like, cool, but isthereanydeal exists.
Up to two years of price history here:
https://isthereanydeal.com/ has 3 years of price history and tracks valid 3rd party stores too (not greymarket sites like G2A).
Price histories for games on both ITAD and gg.deals seem to go back to 2014.
I forgot that since I usually just check 6 months/1y/3y but they do huh. Even better!
It’s also worth checking out their Augmented Steam extension to get a lot of that directly on Steam Store pages.
Is it only two years? I feel like I’ve seen more. I always consult it before buying any game. Feeds my sales addiction.
They also have a browser extension to put some additional info right on the steam store pages.
Not the entire price history, but it will show the lowest ever price, and the last time it happened. Even if Valve puts a 30-day history on the page, this would still be useful to know if a game ever gets discounts deeper than whatever it had most recently.
