If you have not used their service yet, take a look at SwapVideoGames.com. They will allow you to purchase a new or used video game and actually pay with your old games. If you do not have enough games to trade in, you can make up the different with a credit card but since you can trade-in up to 8 games on each transaction, it is very possible to get your entire transaction for no cost. They even pay for the shipping and send you a postage paid return mailer to send in your old games.

I know you are thinking..... yea, this sounds good, but how long does it take? Well that is the beauty of the site, they SEND YOU THE GAME YOU ARE PURCHASING FIRST. Included with your purchased game, you will receive a postage paid return mailer to mail back your trade-ins. You do not have to wait for them to receive your trade-ins before they send the game you are receiving, you will generally receive your game 3-5 days after ordering.

You can also PRE-ORDER new release games 2-3 weeks before they come out and LOCK IN the value of your used games.
