Where can I buy cheap clip-on Hair Extensions?

I live in Los Angeles.


I know I can buy some at Sally's Beauty Supply,


but I want to know if there are any other places I can go.


The ones I want (at Sally's) are the Paris Hilton Clip-N-Go Extensions.


But they're 18'; long and I want them to be at least 10-14';.


If not I would just cut them myself.


And my hair is dyed blue black.Where can I buy cheap clip-on Hair Extensions?
My recommendation for hair extensions is to check a local hair extensions directory, something like the hairextensionguide.com they go over the best hair extensions salons all over the world, and most people can find a hair extensions salon in their area that way. They have many listings of hair extensions salons.
