pedela Sisters

Hey ladies-

I know there was just a thread about them recently...

So I emailed both sisters and they quoted me at $650 each, for a half a day (4 girls) From what i am finding online though it seems that they usually charge (or maybe use to charge) $350.

Does anyone know what the story is? or have any advice on how to ask the sisters about it (I am soooo bad with negotiating). TIA
