When you're tired of your older Xbox, Wii, PlayStation, and PSP games, consider selling those old video games through a store's trade-in program. It's not always easy to sell old video games for a reasonable price on auction sites -- in the local classifieds -- because many people can find new games at deep discounts on older games elsewhere. You might end having to pay fees to list your items in the local newspaper, and trying to sell video games at a garage sale can be challenging.
