[Amazon PC DD] Borderlands 2 $10.19 (Cheaper Than Steam's Deal Today)
As per title it looks like Amazon are price matching Steam on the daily 2K deal, is a pretty good price, has only been cheaper on GetGamesGo once before.
Borderlands 1 GOTY is 14.99 also though this is less of a deal
Both games register on Steam
