Wanted to post this here, in case other might have the same luck. My local Walmart store has just put out one of those large bins full of clearance video games. Ranging all modern consoles, new and "Walmart pre-owned" and prices from $5 - $19.99. I was able to find Mega Man Collection (PS4) for only $5, and Super Smash Bros Brawl (Wii) for $15.
This is a "your mileage may vary" deal, it might not be occurring at all stores, and all stores might not have the same stock. But, it's worth a shot.
