Actually It seems the 1.24$ price point is quite big on the Best Discount in SteamDB list and the <=0.99$ even larger...
I think I'm giving up for now and may not get to complete it, so these are good additions :)
To make it clear, My list is far from being a Complete listing, But it does skip all Bundled items (spare one).
I chose titles I found interesting with Good reviews (though some of the newer titles only had a few dozen reviews altogether).
Also, these 4 SteamDB list as a Special Promotion? and I didn't check them so far:
Android John Game -80% $0.99
Beat Da Beat Game -75% $1.99
Salvation Prophecy Game -90% $1.99
Space Bit Attack Game -80% $0.99
BlackThorny: And on a side note, why is
Kult: Heretic Kingdoms Not yet on Gog?!
Impaler26: It is available on GOG since years already. ;)
https://www.gog.com/game/heretic_kingdoms_the_inquisition I knew
It looked way too familiar, so it was very strange IsThereAnyDeal didn't list it on Gog...
Why is there such a name discrepancy between platforms?
