I can disprove your point. I shop around, I'm sure many others do, I will buy from whoever sells at the best prices, I don't impulse buy. But the plastic film on a new copy means everything to me. I would rather buy new and support the industry I love. Anecdotal evidence means nothing. The crazy thing is, I'm not even trying to put what your doing down. I encourage you to trade in if you like. What I am trying to discourage is the notion that your one copy of the game means anything to a company as large as Activision. It's a drop in the ocean to them. I'd also consider trading in in store. Some of them offer a decent, set price and you won't be involved in a bidding war against dozens of other sellers. Either way, claw back as much of your money as you can and good luck.
