Normally $89.95 for 12 months. Now $67.45 until the 26th. Unlike the deal going on on the PlayStation store existing subscribers can use the deal. I couldn’t see a purchase option online(despite them have a banner that links you to the stores page), so it might be in store only.
Free games this month are Call of Duty Modern Warfare remastered and the Witness. But the primary reason for PSplus is online gaming, just remember you don’t need PSplus if you only play Free to Play games like Fortnite, Warframe, World of tanks, Apex Legends, Smite, Let it Die and the like.
