GAME have launched their online price checker service for used game trade-ins. It's been a long time coming but the retailer has finally allowed gamers to find out what they will get when they trade their games in within their stores. The service is a little long-Winded however, more so than the rival service offered by CEX. The service requires users to enter the barcode of the game they want to sell and complete a CAPTCHA form before they can find out its value in both cash and credit. The troubled retailer is currently offering 25% extra on trade-ins until the end of May.
