Since it’s Steam sale season, a lot of people have been asking about sites that find the lowest Steam key prices, but you can actually solve this just by installing one add-on right on the Steam webpage.

It’s an add-on called “Augmented Steam,” made by isthereanydeal (which is widely referenced). If you install it and check the Steam page, you can instantly see where the current lowest price is and what the historical low price was, right on the Steam page. Just note that it won't show Korean local shops like DirectGames or Stove, so you’ll need to check those separately if necessary.

You can install it here: https://augmentedsteam.com/

This is what the Wishlist looks like:

And this is what shows up when you go to an individual game's page:

It usually works on lists like the 'Popular Games' page too, but the Steam layout seems to have changed slightly because of the sale period so it might not be showing up. This stuff usually gets updated within a few days, so NBD.
