Magento

Hi
Couple day ago I called to web store to buy some stuff. During that call we negotieted price, free shiping, bonuses etc.
I was stunned when they asked me for email adres, in 2 min I got link on email with prepered order with all things that we agreed on the phone. All I have to do I pay for it
Do any of You know any extension that can do that?

Very interested in this extension.
