Another way to find the best deals easily during Steam Sales ...

https://steamdb.info/sales/?min_discount=50&min_rating=60&min_reviews=500&os=steamdeck&sort=id_desc%2Crating_desc%2Cdiscount_desc

I have this bookmarked and this is how I consume every sale.

It adds a bunch of filters to try to ensure the best quality games at the best price.

It requires a 50% or more discount, 60%+ rating, at least 500 reviews and filter it on by Steam Deck.

Beats browsing by hand, I'll tell ya that. Enjoy.
