Buying used video games at places such as GameStop versus new can save you a good chunk of change.
Now Walmart wants a piece of the used video game action.
The store chain recently began selling used video games online.
That followed Walmart announcing its video game buy back program in May, where customers could return games for store credit.
Those returned games are now being sold for 15 to 30 percent less than if they were new.
Then again, if this thing takes off, you won't need games on discs anymore, making the used video game business a thing of the past.
But that may be years down the road if it's successful. People have been able to download their music for years but many still prefer to buy them on discs, or CDs.
