I noticed it has a great price for the Dinc 2 on Wirefly.com, but how is Wirefly.com? Also, how does it work if I am re-upping a contract? Would I buy the phones, our current phones would be deactivated and have to wait for the new phones to come in? How does it work? Would be very grateful to hear information on how sites like this (also Amazon Wireless and Newegg) work.
