Just for the record, half.com is a startup entity that was bought out by eBay (and at quite a windfall for those involved). It's not really a hot deal to post, but OTOH, you can get lots of good stuff cheap from here, so if you don't know of it, you do now
I prefer it to *bay b/c you don't deal directly with the seller, shipping costs are fixed by half.com and you don't have to bid and hope to win.
FWIW, I've bought a number of items from half.com (CDs and DVDs). So far I have not been snubbed or screwed. I always buy from users with high ratings and I typically only buy stuff that specifically says that it is new and sealed, or VERY descriptive about what's included.
FWelseIW, I was just reading something on DVDTalk (search for Dreamcast) about a guy who bought a DC game and got a burned copy. I just ordered 3 DC games from there...I'll let you know how I fare. All specified that they were new and sealed with all documentation.
