Okay go into the store and look for a game you want to rent. This will only work if the game you wish to rent IS NOT there and you can ask to have it mailed to you when one is available. Here's what I did, I did not do this intentionally, but just got lucky. This was about 2 months ago, but I just decided to post it now.

NOTE: I guess it's not a "FREE" game, but its only $7, rather than $60. Also this will work better with new and popular games as they are usually not there.

Okay so they say my game will arrive in 2 business days(MLB 2K10), I wait 3 days and still no game. So I call and the lady says she will send another one. Now I check my email and she marks that I returned the first game, because something happened where I did not receive it. So the next day the FIRST game comes, the one she said I returned. Then 2 days later the SECOND game comes. So in 5 days I send the second game back and keep the first one, they probably just think it got lost or the order was messed up. Anyways I get a $60 new game, for the price of $7.

I don't know if this will work more than once, probably not with the same person answering the phone cuz they will catch on. But the lady I talked to on the phone didn't seem too bright so thats probably why it was so easy for me.

Like I said earlier, I did not intend for me to get 2 games, but I got lucky. I have not received an email from them saying anything about the game, so I'm fine. Tell me if this helps.
