How much could my xbox sell for?

well doing retail value for October 2009 I would say your whole bundle would go for, *thinks* >.<' close to 500+ dollars, since I only see a few of your titles. But do "NOTE" that businesses want to make a profit, and you will "NOT" be able to sell it for that much, or "EVEN" 50% of its value. No they'll give you 30 - 33% of its value, at best, sorry to say, so I would advise you to take a calculator, put in 550, multiply it by 0.33, then I want you to add 30 more dollars to that. Whatever the outcome, go in, try to sell them for that price, and then haggle. You'll make some penny, but not as much as you wish. Sorry mate, the world is about making money, they want to keep as much as they can, you want to get as much as you can, I wish you luck, and OH, Favor me :P I wants me some 10 bonus points :P if you do what I advised. Peace
