I have been having rather good luck and saving sometimes over 40% to 60% on normal MSRP, by buying slightly used things from the better rated sellers on Amazon.

I have stuck to used stuff my whole life. Started this trend when I was a kid and discovered I could buy a lot more Nintendo games by getting them used rather than new. VHS tapes were always a little iffy, I had bought a few used ones that had problems, so I stopped with those. But I have never had any problems with used CDs, DVDs, or CD/DVD-ROM games. Most places won't buy things that are badly scratched, and I have never found a used place that won't take things back if they don't work.

Through amazon I have never had any serious problems either, just stick to people with good feedback. Any times I have had problems, I have never had any trouble getting my money back.

In fact, in all my years of buying used stuff, the only time I ended up with some badly scratched discs and a seller unwilling to do anything about it, was when I bought the collector's edition of Halo 3 on ebay for $15 bucks. The seller listed it as "very good" condition, but due to the H3 collector's edition tin being really poorly designed, and not holding the discs very tightly, they became disloged during shipping and got the shit scratched out of them (turns out this was a huge issue when the game was first released too, many people picked the game up on release day and were unable to play it because it was so badly scratched). Fortunately, they still work well enough and I got a good deal on them, but it was still disappointing.
