Went to a different store tonight and found a couple of other games. All at $7 each.
Dark Souls II(XO) - 2 copies, 1 tagged $7 and the other $19.88. Asked for the $7 one and it rang up $19.88 but got an override for the lower price
Wolfenstein: The Old Blood(XO) - they had copies for both XO and PS4 but went with the XO since it was actually tagged $7
Zombie Army Trilogy(PS4) - not tagged, but did a quick check on brickseek after seeing someone else mention it being cheap
There were probably some other cheap titles to be had as they had a ton of games for the XO, 360, PS3 and PS4 lined across the bottom of the glass cases. While most weren't marked with a price, quite a few were tagged $19.88 and even noticed a couple of $9 titles(NBA16 was one), but there were way too many to stand and check each one on brickseek.
Its quicker to throw a bunch in a cart and go find the closest price checker.
