Don't get ripped off by anime bootlegs. Words to watch out for : extra cheap + 'import set' (the real Japanese DVDs tend to cost double what we pay for a DVD in the US), 'all region' or 'region 0' (near all anime DVDs that are licensed are 'region 1'(this is for North Americans), Chinese subtitles, etc.
Why should you care? First, you're paying for something that will probably not have the best translation or picture quality, second, you're paying for what you could get for free. If you're going to pirate, don't pay to pirate. Third, anime companies put out what is profitable. If you're getting ripped off on your favorite show, it's sequel might not come over. So remember, don't be dumb, get a real one!
