Used to work at EB Games a long time ago, before Gamestopo bought them.
As a consumer you can never find a true deal at stores like these because anything under a certain profit margin we simply throw away instead of selling.
For example, if customer A brings us a game that we give him a quarter for, its not like we sell that game for 50 cents so the next person can play it. We put it in a box and its considered de-inventorized which means either we throw it away or mail it to corporate so they can throw it away. We only bought it for a quarter in the first place because removing older games from the market is pivotal in being able to charge an arm and a leg for new games.
And the games you are told are 'new' are not new unless they are in factory sealed boxes.
If you are given a game that needs to be put in its case, it insnt new. We used to play those games at closing, or take them home and bring them back the next day. Especially the DVDs once we started taking in movies.
There is a shytload of inventory at all times that technically we have in stock that is priced at $0.01 (a penny) that we don't stock and is just sitting in the back in a box waiting to be thrown away. I spent a dime one day and left with a madcats racing wheel (the big one with the foot pedals and shifter) an e-card reader... all types of stuff.
Those stores don't care about you. Anyone that works there that does is quickly out of a job.
A while back an employee at gamestop tried to sell me an open game as "new". I was like
what are you doing? Are you going to charge me full price for that? And he comes back with, "Yes, it's a NEW game. It hasn't been played. We use the boxes for display sometimes". 
"What the heck is the difference between that and a used game then!?"Manager comes over and gives me the game at the pre-owned price.

$100 from $500...closer to $75. 
"Wait a min, I want a new game" then they said it to me, It's a new game and I hit
"Never mind, I'm going to Best Buy to buy a "NEW" game unlike you piece of shyt". 

You cant do that"
Watch me
