I just came back from walmart in Norwalk, CT and they had a bunch of Soundblaster Live 5.1 X-Gamers and Mp3+ for $50 on clearance. These were retail packages and they seemed to have a decent amount of them. Don't know if this is a local thing or not. Either way this is little more than what the OEM SB Lives are going for so if you can't get in on that staples deal this might be a potential good deal for you.
