I'm not sure...are you in the UK? If you are I could probably find you a good deal. If you're not...uh, try Gamestop? xD
Sorry, it wasn't intentional...although you saying that makes me feel old. xD;
I would, if I had the opportunity to do so - they're denying you something you enjoy! Or, at least, making it more difficult than it ought to be for you to get new games. Either way, the "you're too old" justification really isn't much of one...
