Three of my closest Best Buy stores have most of their PS Vita games on clearance. These games are not listed at all or at these prices on the website clearance, website in-store clearance or BB in-store app.
Here's what I was seeing:
Rayman Legends - $14.99
Uncharted: Golden Abyss - $17.99/21.99
Tearaway - $21.99
Assassins Creed 3: Liberation - $19.99
Injustice - $14.99
Gravity Rush - $9.99
FIFA Soccer 13 - $9.99/14.99
Batman Arkham Origins: Blackgate - $14.99
I noticed a few games like Sly Cooper, Smart As and Wipeout 2048 were marked "clearance" for 9.99, but they are currently on sale online for the same price. It seemed that between each store I went to, every game in stock outside of Borderlands 2 & The Walking Dead were on clearance. That may not be saying much since most BB have a limited Vita selection though.
Hope this helps!
