How can I be sure this item is working
I can show you that it works.
So I can test this out before purchase right?
Sure, and it is still under warranty.
Do I need an extra power cord for this phone?
It comes with everything needed. I guarantee it works fine and you'll love it.
Will you knock a few bucks off the price if I offer to pick up in the next hour?
Sure what did you have in mind?
