A few weeks ago, GOG ran their summer sale and I got a bunch for a very fair amount.
Right now the european PS Store has some great deals on too (Kiwami and Zero for £11,99/€14.99, Phantom Pain £6,49/€7,99, and a few more depending on what you're into. I'll highlight one that might go under the radar: EDF 4.1 at £8,99/€9,99).
Steam and Itch.io are also running their summer sales but the amount of games on offer is so huge I can't possibly scroll through it all. I intend to get Hollow Knight at least. If you have any more suggestions, please share them here...
