Step 1 Get Money
First you need to find a way to get 60 dollars or less, depending on what game you are going to choose to rent.
Step 2 Visit GameStop
When you get inside GameStop, you have to choose a pre-owned game that you like. It could be any game, just make sure it is pre-owned.
Step 3 Ready PowerUp Rewards
When you get the pre-owned game of your choice, take it up to the counter and make sure you have an active PowerUp Rewards card/account.
Step 4 Pay the Money
You can either pay for it in store credit or cash, whichever you prefer.
Step 5 The Con
Now that you have the game of your choice, you will be able to start the free renting process.
Step 6 Return Policy
So the return policy with all pre-owned games is that you can take it back within a week, for many reasons, whether you say it doesn't work or that you just don't like it, and they will give you a full refund.
Step 7 (Almost) Free Renting
Get it? So, you can now get free unlimited weeklong rentals from GameStop by buying a game of your choice, taking it back within a week and choosing a different game. Then, repeat the process over and over again. It's free! You're just out the cost of the initial investment.
I have done this many, many times and have gotten new release games such as Halo: Reach, Fallout: New Vegas, Dead Space 2, Call of Duty: Black Ops, Red Dead Redemption, Borderlands and many more— all for free, thanks to this great loophole in GameStop's system. So, try this out sometime and you will never spend money on renting games again!
