I got mine from Anime Discount DVD. ^^ It is a pretty decent site. The 8 DVD set of the whole series was actually $100 US. But they also had the TV series plus both movies on sale for about $115. I'm not sure if it's still that way, but I just went for the series, since I already have the movies on video.

I plan to get 'Orphen Revenge' and 'Princess Mononoke' as soon as I get my CCS DVDs and find out what kind of quality I'm paying for. :)

Not just for Touya/Yuki... though I love them. I really like Shaoran/Sakura, too. And it's also really cute when those two both love Yuki. Hehe. :)
