My best friend bought i think it was 9 clips for $100, she wanted black ones but they would have cost her alot more so she bought blonde ones and she dyed them black herself and she curled them and then put them in. They actually looked really nice. She has tried real extensions but they all fell out and ripped half her hair out so the clips are more effective. And because she dyed the clips themselves you didn't see them when your hair moved, specially if your hair is quite thin.

I have no idea where she got them from, but it was an aussie site i do believe.

HTH.
