If you want to save some bucks and stock up on handheld titles, you need to start paying attention to the PSN.
As noted by GamingVlogNetwork , more than a few Vita and PSP games have received discounts, of which you can take advantage if you're a PlayStation Plus member. You are, right?
The discounts range between 30% and 50% off and this week, you can grab Virtua Tennis 4: World Tour for $19.59 (down from $27.99), Hot Shots Golf: World Invitational for $17.63 (down from $25.19), Hustle Kings for only $4.89 (down from $6.99), Madden NFL 12 for the PSP for $9.79 (down from $13.99), and NBA 2K12 for the PSP for the same price. I say if you haven't played the Hot Shots for the Vita just yet, you're absolutely missing out, but there might be other titles that catch your eye.
The Plus membership has definitely paid for itself a few times over by now, hasn't it? If you haven't given it a whirl, you should definitely consider it. Beyond discounts, other benefits like early access to demos and betas make it plenty worthwhile.
