All three versions of Ghost Recon: Wildlands for PS4 can be had at a discount: standard ($51), Deluxe ($59.49), and Gold ($85). That's only a 15% discount on each, but given the game was just released earlier this month, it's awfully soon for a sale on the digital version.
The Resident Evil series is featured in its own sale, discounting games on all platforms. Among the highlights are Resident Evil, Resident Evil 0, and Resident Evil 4 for $10 each on PS4 or PS3. The PS1 Classics versions of Resident Evil 2 and Resident Evil 3 (playable on Vita, PS3, or PSP) are $1.49 each. Resident Evil 7 remains full price, but its Deluxe edition can be had for $75 (down from $90).
PlayStation Plus members get their own exclusive sale that offers For Honor for $48, Mafia III for $30, Lara Croft Go for $5 (PS4/Vita Cross-Buy), The Elder Scrolls V: Skyrim Special Edition for $30, Watch Dogs 2 for $36, Zero Escape: Zero Time Dilemma for $20.
Finally, the ongoing buy one, get one free sale remains live until April 11.
