I stopped by my local Sony Store and they have a sale (not sure for how long) on their clearance Playstation 3 and Vita games. The sale is 50% off the clearance price of the games when you buy 2 or more, your YMMV.
I stopped by a regular Sony story in my area and they had no clearance. However the outlet mall Sony Story had plenty of clearance all 50% off lowest marked price
Here's what I picked up: (all prices after 50% discount)
Vita:
Reality Fighters $4.98
Lego Harry Potter $7.48
Asphalt Injection $7.48
Rayman Origins $7.48
Little Deviants $4.98
RidgeRacer $4.98
Hot Shot Golf $4.98
BlazBlue: Continuum Shift Extend $4.98
Ultimate Marvel Vs. Capcom $9.98
This was pretty much it for Vita games.
I also saw Modnation Racers & maybe one more
PS3
Little Big Planet Karting $14.98
There were probably 8-10 other PS3 games but I was in a hurry as I hate the outlet mall on the weekend its a zoo!
I'll try and go back on monday and take a photo of the games There were also some vita accessories on clearance but their prices have been cheaper
