Yup this is what I mean, I spotted the CE on ebay for 15/20 bux about 2 weeks ago.
As far as buying video games from ebay goes, for what it's worth I started to do it since Baldurs Gate 2 and haven't had a problem yet.
I usually go for mint condition/unopened games but have bought one or 2 that were used a little again no problems tho, I always get a great deal too and i'd recommend it to everyone. Just read the sellers ratings/reviews to see if they're good on delivery/timing etc. Basically you will get at least 10 dollars of most games there...at best games sell for dirt cheap (like neverwinter nights is now).
Give it a look and see, beware though... ebay is addictive
